After the second half of last year all the major manufacturers of flash memory has started to produce multilayer chips with 64 layers, we began to actively look at a variety of SSD, using exactly the same semiconductor base. As you know, Samsung uses in its own storage 3D NAND chips in different levels of integration for a long time, and based on them products cause only positive emotions. But other manufacturers of flash memory, particularly Toshiba, Intel, Toshiba and Sandisk, until recently lagged considerably behind South Korean firms to improve their own versions of the three-dimensional flash memory. To catch up with the leader they did it only when moving to 64-layer design 3D NAND that Samsung competitors received a dramatic improvement compared to previous versions. So today we can say that the key benefits of the products on the basis of the three-dimensional memory manifest itself in any solid-state drive based on the 64 layer 3D NAND, regardless of the memory of some of the manufacturers used in each case. In other words, focusing on products, built on a 64-layer 3D NAND, you are likely to get productive and very reliable drive with a fairly attractive price.

The only problem is that until a new generation of three-dimensional memory is not widespread. Apparently, manufacturers there are some production difficulties that do not allow 64-layer memory to begin expansion on a broad front. And at the moment drives based on this memory, I suggest either only by manufacturers of NAND chips, or their very close associates. For example, if we talk about SATA SSD, the stores are only a few built on a 64-layer 3D NAND mass models: 860 Samsung EVO, Crucial MX500, 545s Intel SSD, Kingston UV500, SanDisk Ultra 3D, R Puls, Western Digital Blue 3D NAND and Toshiba TR200. And half the models on this list available is very limited.

In these circumstances the appearance on the market some new models, built on current versions of the three-dimensional memory, can only be welcomed. Fortunately, the number of suppliers of the SSD gradually join the producers of the second echelon. One of the first to work with the 64-layer memory purchased from Toshiba, Plextor. Being a subsidiary of a major OEM manufacturer Lite-On, Plextor has a strong engineering capabilities, and its SSD each time represent a very original and very interesting on the characteristics of the products. It happened at this time. The first SSD based 64-layer TLC 3D NAND Toshiba (BiCS3), Plextor released, became NVMe drive Plextor M9Pe, which was quite good for an inexpensive solution with PCIe 3.0 x4. But today we will talk about the second brainchild of the engineers of Plextor, which followed M9Pe designed a more public model M8V SATA.

Immediately is to say that from a technological point of view, Plextor M8V – a very interesting and unique solution. The fact that it BiCS3 Toshiba memory operates under control of controller Silicon Motion, which is usually only used memory Intel or Micron. But the developers of Plextor managed to combine the components before us to be seen together never had. That is why Plextor M8V and caught our attention. SATA drives based on BiSC3 memory, tested in the laboratory 3DNews before, used the Marvell or Phison controllers and showed relatively good performance. However, Silicon Motion recent progress in the development of their controllers stronger competitors, so we do not exclude that Plextor M8V will be the best demonstration of the advantages BiCS3 NAND. It only remains to verify in practice.

#Specifications

The basis Plextor M8V elected controller Silicon Motion SM2258. It is not the latest SATA controller the developer, but the most common. The first time we ran into him at the beginning of 2016, and now it is widely used in SSDS with 32-layer 3D NAND flash from Intel or Micron. In addition, it is possible to find promising innovations, for example, Crucial MX500 drive of the latest generation, built on a 64-layer 3D NAND Micron authorship. The popularity of chip SM2258 is due to the best combination of performance and price. This controller relates to a number of relatively low-cost solutions: it is based on a single-core 32-bit RISC processor for interaction with an array of flash memory offers only four channels. However, the finished product usually obtained is quite good from the point of view of performance: this software helps in optimization with a focus on minimal latency when processing mixed operations and technology dynamic SLC caching.

At the same time, together with Toshiba BiCS3 memory one can use the controller SM2258 never tried, and Plextor in this regard – a pioneer. In theory no problems with it should not be. On the one hand, in the controller there is support for technology NANDXtend, within which strong algorithms of error correction based on LDPC codes, which should be a guarantee of the reliability of the platform. On the other – is itself BiSC3-memory is a kind of 64-layer TLC 3D NAND, provides a good level of performance, especially when compared with planar flash memory. In this we see when testing, for example, drive R Puls. Most importantly, unlike the Samsung, Toshiba proposes to install in SATA SSD crystals NAND capacity of 256 GB, which allows to obtain arrays of flash memory with a high degree of parallelism.

The result M8V Plextor boasts of the following set specification:

To be honest, the Datasheet doesn’t look too promising. Plextor has included in the lineup M8V only version of the small volumes (less than half a terabyte), and this clearly indicates that the company believes the new entry-level product that should find its place in a relatively cheap builds. Does not emit much optimism and announced the terms of the warranty. Three years is a typical value for a storage low level, though allowed amounts of rewriting is relatively good. The hypothetical user is allowed to overwrite the half of the SSD capacity daily.

It turns out that the position of the SATA Plextor flagship M8V attack and does not intend, and this is reflected including in the announced performance. If you believe these numbers, then at the moment M8V Plextor is one of the weakest SATA SSD, built on a 64-layer TLC 3D NAND. Even budget drive Toshiba TR200, in which the array BiCS3 devices is controlled by dual-channel UN-buffered controller Phison S11, the list of passport characteristics promises higher performance.

However, declared by the manufacturers characteristics of the performance not always depict a picture adequately, because they did not report the implementation of the technology rapid entry has become an integral attribute of a modern SSD. To get clarity on this question, we conduct a special test, in which check the performance of continuous serial write on a clean drive. In the case M8V Plextor 512GB dependence is the following.

And here it turns out two important circumstances.

First, the engineers of Plextor hacked at the root one of the important advantages of the controller SM2258 – dynamic SLC caching. In M8V instead implemented quite ordinary static SLC cache, which is not available in the user region of the array of flash memory. And this cache has a relatively small size. The storage capacity of 512 GB with only 4 GB. So, in versions M8V a capacity of 256 and 128 GB SLC cache has a capacity of 2 and 1 GB respectively.

Second, the array of flash memory-based devices BiCS3 works under control of the controller SM2258 clearly not the best way. So, M8V Plextor 512 GB speed direct linear memory writes is about 330 MB/s. But at the same time similar in composition and organization of the array of flash memory for use with the Phison S10 controller produces 450 MB/s (for example, Smartbuy Puls), and the array of the 64-layer devices Toshiba 3D NAND TLC when working with the controller SM2258 able to receive data at a speed of 420 MB/s (e.g., Crucial MX500). It turns out that by combining the Silicon Motion controller with a three-dimensional memory Toshiba, the developers of Plextor’s absolutely nothing won, but rather lost, at least from the point of view of the performance of the linear record.

However, to classify the Plextor M8V among the outsiders also should not be. Write speeds of 330 MB/s is not so little. For example, the new Samsung EVO 860 in polterabayta the volume is even slower array of the flash memory. Besides, Plextor did not skimp on the DRAM buffer, and even more, did it twice more capacious compared to the typical size. This means that M8V can be a good solution for arbitrary melkoplodnyj loads, for which the controller is actively used memory.

#Appearance and internal structure

Discuss in this review the drive exists in two versions: in the traditional 2.5-inch form factor (M8VC) and M. 2 2280 module with SATA interface (M8VG). Both of these modifications are functionally identical. Therefore, getting acquainted with the 2.5-inch model, we automatically generalize all findings to all family M8V.

For the tests we were given the option of drive capacity of 512 GB is the eldest and the most productive model in the family. This SSD 2.5-inch version was not surprised by its appearance: it Plextor have not changed for the last few years. The casing is made of unpainted aluminium, with traces of processing. On the front side of the paint manufacturer’s logo, the back has a sticker with technical information.

 

Note that Plextor does not hide the label nor a release date drive or uploaded at the factory firmware version.

The housing mounted circuit Board, occupying slightly less than half of the internal space. Full Board in modern drives are no longer used: manufacturers of flash memory have learned to do such chips NAND, which can accommodate up to 1 TB of memory a few crystals of NAND, so to squander the PCB makes no sense. Capacious SSD can be done using two or four chip flash memory.

This is the case and Plextor M8V volume of 512 GB. Despite the fact that it is the older version in the lineup, an array of NAND in it, typed four TSOP-chips Toshiba TH58TFT0T23TA2H. Each chip is Packed in four 256-Gigabit semiconductor crystal 64-layer BiCS3-a three-bit memory cells. This means that the four channel array of the flash memory in M8V 512GB uses a fourfold alternating devices in the channels.

 

Manages the array controller SMI SM2258. The design M8V uses exactly the same version controller as in Crucial MX500. That is, no modifications to implement support BiCS3 in a base chip to do not have: compatibility achieved software-only effort. Note that Plextor M8V controller without any pads. However, this is not a problem: SSD temperature during operation remains very low.

In addition to the NAND chips and controller on the motherboard M8V placed and released by Samsung chip DDR3L-1600 SDRAM used as a buffer when melkoplodnyj operations and to store a copy of the table of address translation. 512-Gigabyte drive this chip has a capacity of 1 GB. Plextor often uses in his drives, DRAM buffer is increased in size, and M8V exception to this rule is not.

Interesting also worth noting is the presence of on-Board storage marking CV8-CE512. It is a reference to the name of identical models produced under the brand name Lite-On. That is, M8V, like many other products of Plextor, has a twin brother in the lineup of the parent company.

It is worth noting that the declared capacity of the representatives of the lineup of Plextor M8V multiples of 128 GB. This means that the manufacturer gives a 93 percent capacity of the array of flash memory, and operating system 512 GB SSD will offer 477 GB free space. The remaining one-third of the volume of activated SLC cache, and two-thirds are involved in the technology of garbage collection and wear-leveling, and is also used as a replacement Fund.

#Software

Before the Plextor was paid to software support for their products very much attention. For storage, the company has developed an extensive set of programs, including “conventional” service tool, and additional tools for caching, compression, and data encryption. However, in early 2017 further development of these software tools was abandoned, but at the moment the old version is quite cope with the tasks assigned to them and even remain compatible with new products, in particular with Plextor M8V.

The main utility for SATA SSDS production Plextor is called PlexTool. By today’s standards, it is not rich in functionality and looks too pretentious, but the basic questions about the drive it reply. Using PlexTool can learn General information about SSD, read the contents of SMART, and get control over the flow of the TRIM command.

 

In addition, the utility can upgrade the firmware of the SSD is estimated to test the performance and serve to drive Secure Erase command.

Another utility, PlexTurbo, you can provide an additional level of caching disk operations using the computer’s memory. This gives you the opportunity to increase the speed of operations is often sagastume files and reduce the load on the drive. However, such software solutions are fraught with potential danger: in the event of unplanned outages or failures of computer data that failed to be written from the RAM cache on the SSD, of course, will be lost.

In addition, storage series M8V PlexTurbo utility functions in abbreviated form: the maximum amount of the generated in-memory cache is limited by the size of 1 Gbytes.

Another program from a set of Plextor – PlexCompressor. This utility is an add-on file system which performs automatic compression of unused files, freeing up extra disk space. Moreover, this compression works very selectively. In order not to create excessive load on the CPU, it affects only those files that are not used by the user at least during the last 30 days. In the same case, when this compressed file will be hit, it will be returned to its original state.

The last utility, which you must tell is PlexVault. It proposes to realize the drive’s data encryption. However, you need to understand that we are not talking about hardware-based encryption, which M8V not implemented, and pure software algorithms, which, when their work load on the CPU.

PlexVault can create one or more encrypted containers, and in normal conditions they are visible only in the program authorized users who know the “secret” key combination and password. However, to use such a tool in serious applications, we still wouldn’t advise — at least because the Plextor not share any information about the used encryption algorithms and does not conduct independent audits of its cryptographic solutions.

A review of the drive, the Gigabyte Aorus RGB M. 2 NVMe SSD: the size of the illumination is not a hindrance

Samsung J7 V just $5 mo. New device payment purchase req'd. Plus, free shipping.

Today’s review is curious at least for two reasons. First – we SSD released by Gigabyte, which drives absolutely not associated. All the same, this Taiwanese manufacturer of motherboards and graphics cards systematically expands the range of devices, adding a range of new and new types of computer equipment. Not so long ago we tested released under the brand name Aorus, Gigabyte the PSU, monitor and RAMand now is the turn to SSDs.

However, to be completely correct, it is necessary to mention that the Toshiba SSD delivers under its own brand for quite a long time. The first drives with the SATA interface it introduced a year ago, but it was not very interesting budget model c quite ordinary characteristics. Now Gigabyte decided to release a real SSD for enthusiasts with a modern interface NVMe 1.3, flagship performance RGB led branded gaming style. That’s why the Gigabyte Aorus RGB M. 2 NVMe SSD, which will be discussed later, and caught our attention.

The second reason that forced us to get more information about this novelty, is that it is based on a relatively new hardware platform, which we have not yet had to face. In the Gigabyte Aorus RGB controller is used PS5012-E12 independent of the Taiwanese company Phison, the development of which in recent times found only in the lower price segments and in high-speed drives do not fall for a long time. But now, apparently, Phison strategy has changed, and the company expects to regain a foothold in consumer drives a higher level.

Actually Phison focused on budget platforms SSD it is not because of some marketing reasons. Her problem was the fact that the process of final debugging and output products to the market, took lots of time, and the proposed Phison decisions were often obsolete. This forced the firm to fight for a place in the market only with the help of low prices, which led to the formation of platforms around its image again.

Such history threatened to repeat itself and with the controller PS5012-E12, as it was first demonstrated at CES 2018 a year and a half ago. However, this time the developers have time to finish your product to its obsolescence. The beginning of deliveries of the platform E12 company Phison announced in September, and now the first actual products based on it and finally got to store shelves.

The appearance of another controller for consumer NVMe drives are very important and need to market the event. Unfortunately, so far nobody has been able to offer a platform for NVMe SSD, which would allow to create a storage class 970 Samsung EVO Plus. New developments of Silicon Motion and Western Digital, as we have seen, are at a lower level. And this means that the South Korean company was able to monopolize the segment of high-performance NVMe SSD, keeping to their flagship drives high prices. That’s why we wait for Samsung EVO Plus 970 and 970 PRO will have some real alternatives, able to do advanced disk performance more accessible to consumers.

On the one hand, characteristics that Phison claims their new controller PS5012-E12, allow us to hope that the power it is at least not worse than Samsung Phoenix. On the other the desire to use this chip in their products have already stated at least two dozen manufacturers of the second and third tier. So, if all goes well, the market for consumer NVMe SSD can be a serious and pleasant for users to change. But don’t be in a hurry, and before you give vent to joy, let us analyze how really good the Gigabyte Aorus RGB platform Phison E12.

#Specifications

Usually the drives on the controller Phison represent typical products, similar to each other in basic characteristics, regardless of which company delivers them to the market. Actually, just like is the case of the Gigabyte Aorus RGB M. 2 NVMe SSD – this SSD is used templated hardware and software architecture with a brand-typical set of components. This means that the characteristics of the considered storage device is similar to any other SSD based on Phison controller PS5012-E12, for example MP510 Corsair, Team Group MP34, Silicon Power P34A80 or Patriot VPN100. You may have drives from different manufacturers can be some individual characteristics, but usually they affect only the exterior.

As for hardware designs, in any of the SSD controller Phison PS5012-E12 is applied to one and the same array of flash memory composed of 256-Gigabit devices BiCS3 (64-crystal layer TLC 3D NAND) manufactured by Toshiba. It is worth mentioning that this is a good flash memory, which is able to provide high performance. For example, similar to the array of flash memory used in drives WD Black SN750, which can be described as NVMe solid-solution average. But Western Digital’s own controller, Phison PS5012-E12 is a completely different story.

Until now, Phison had time to check two basic chips for NVMe SSD. First, PS5007-E7, was intended to create a planar drives based on MLC memory, however, despite the eight-channel architecture, was not very productive and was used in a fairly small number of models. The following controller, PS5008-E8, focused on support for 3D TLC NAND and won much popularity, but it was a frankly budget solution with four channels for the organization of the array of flash memory, a stripped-down PCI Express 3.0 x2 and without LDPC coding.

Phison PS5012-E12 on the background of previous chips – the solution to a completely different kind, designed from scratch. Here everything is done in accordance with modern standards. Supported PCI Express 3.0 x4 bandwidth to 3.94 GB/s and NVMe Protocol 1.3. The array of the flash memory is formed on a productive eight-channel scheme. It supports not only modern, but also promising types of flash memory. Support powerful methods of error correction based on LDPC codes. As the DRAM buffer can be used not only for DDR3L and DDR4 memory. Finally, for the production of chips PS5012-E12 used 28-nm process technology by TSMC, while earlier chip Phison ordered from UMC, where they were made on 40-nm standards.

Its new development Phison estimates are so optimistic, that does not hesitate to promise the performance of up to 600 thousand IOPS on deeply pipelined melkoplodnyj operations. And if this number is true, it can be argued that the theoretical power PS5012-E12 is much larger than the SMI SM2262EN, and almost reaches the level of Samsung Phoenix. In reality, however, believe that the performance of the controller PS5012-E12 hard enough. The fact that it is based on the ARM processor with only two cores, while the Samsung solution is based on pachydermia design.

And this is reflected in the characteristics of products that inform providers of final decisions on the chip Phison PS5012-E12. For example, for the drive of Gigabyte come in the following specifications.

Despite the fact that Phison has touted its platform as a solution to E12 flagship level, the formal characteristics of the performance of the Gigabyte Aorus RGB M. 2 NVMe SSD noticeably weaker indicators not only 970 Samsung EVO Plus, but these drives as WD Black or SN750 ADATA XPG SX8200 Pro. And it’s not immediately sets in a positive way in relation to innovations.

Not encouraging, and the work Gigabyte Aorus RGB M. 2 NVMe SSD technology SLC-cache. The engineers at Phison in its new platform and are unable to develop a progressive dynamic algorithms and continue to rely on static SLC cache that the drive capacity of 256GB has a capacity of 6 GB, and 512 GB version – 12 GB. Specifications recording speed according to tradition belong to the accelerated mode, if to speak about direct writes to the TLC memory, its performance is about three and a half times lower. We illustrate this with a traditional schedule speed continuous sequential write on an empty Gigabyte Aorus RGB M. 2 NVMe SSD with a capacity of 512 GB.

The speed entries in the SLC cache reaches 2.0 GB/s, but this performance is very long, on the main array of flash memory write speed is only about 560 MB/s And this, incidentally, is considerably lower than the speed that produces a similar brand architecture of the array of flash memory WD Black SN750. Ultimately, to fully populate Gigabyte Aorus RGB NVMe M. 2 SSD 512 GB, you need to spend about 15 minutes, while the flagship NVMe drive Western Digital you can record one and a half times faster.

In addition, Phison adopted from Silicon Motion the idea of using SLC cache for “cheating” – increase the measurement speed reading benchmarks. Information included in the SLC cache, linger in it for a while to provide the best performance when accessing files that were recorded just. You can see this with a simple experiment, during which we check the speed of random melkoplodnogo read data from a file created on the Gigabyte Aorus RGB NVMe M. 2 SSD 512 GB, as immediately after the recording and after this the SSD was recorded some more information.

As can be seen from the graph, when a fresh test file is excluded from the SLC cache and then write additional 12 GB data read speed is reduced by about a quarter. This means that the simple benchmarks that measure the performance when using applications with a newly created file will display for the Gigabyte Aorus RGB NVMe M. 2 SSD to significantly inflated performance compared to the performance that is possible in actual use this drive.

In the end, the familiarity with the platform underlying the Gigabyte Aorus RGB NVMe M. 2 SSD leaves a reasonable doubt that the drive is legitimate to put on a par with the flagship NVMe SSD. However, this is obviously not a budget option, because the configuration of these drives does not involve any explicit savings in design. Moreover, if we talk specifically about the Gigabyte drive, it is sold much more expensive alternatives on the basis of the SMI controller SM2262EN, the performance of which can be attributed to the average level.

In addition, the Gigabyte Aorus RGB NVMe M. 2 SSD shows up pretty good warranty conditions. The warranty period is five years, and during this time the drive is allowed to overwrite the approximately 1500 times. This allowed even higher than the flagship drives, the manufacturers of the first echelon.

At the end of the story about the technical characteristics remains to notice an odd detail. The model number of the Gigabyte Aorus RGB M. 2 NVMe SSDS consists of two versions – 256GB and 512GB. No option for 1 Tbyte looks very suspicious: such capacity is not only popular among customers, but could allow to obtain better performance by increasing the degree of parallelism of the array of flash memory. Obviously the reason for its absence lies not in the features of the platform Phison E12, as other manufacturers offer and even dvuhterabaytnye terabyte drives based on it.

#Appearance and internal structure

For testing RGB Aorus M. 2 NVMe SSD AMD has provided elder and more powerful modification with a capacity of 512 GB. The drive was made in a typical form factor M. 2 2280, but its appearance can hardly be called ordinary.

Developers of Gigabyte showed remarkable imagination and has equipped its product with a massive radiator RGB led in a corporate style. Due to this, Aorus RGB NVMe M. 2 SSD not only markedly different from any other platform Phison E12, but is one of the most original NVMe SSD on the market, at least if we talk about the exterior.

Radiator mounted in the Gigabyte Aorus RGB NVMe M. 2 SSD, it seems very effective solution. It is not usual in such cases, a thin aluminum plate, and a fairly massive bar with two sawn along the edges of the grooves.

 

In reality, however, removes heat from drive, it mediocre, because the developers of Gigabyte does not care about its tight fit to the cooled components. Due to the fact that the height of the controller IC is lower than the height of chip flash memory, core chip SSD that radiator is almost not cooled. In addition, no heat sink is forced to do the memory contained on the reverse side of the M. 2 module. In other words, the entire cooling system is more of a decoration.

However, the scenery was quite spectacular: at the center of the radiator flaunts a logo Aorus – head eagle – with RGB led backlight. When the logo cyclically pulsates different colors. Strictly speaking, the backlight can be configured using the utility RGB Fusion 2.0, but this feature is available only for selected models of Gigabyte motherboards. In the compatibility list includes only the fee Aorus Intel Z390 and fee X299 Aorus Master. On any other motherboards algorithm of the backlight control does not work.

Usually all the drives are built on platforms Phison, use the same PCB design, provided by the authors of the controller. However, the Gigabyte Aorus RGB M. 2 NVMe SSD received a slightly modified PCB. On the Board added two holes for screw fastening of a radiator and three RGB LEDs, which illuminate the Aorus logo. But otherwise the layout of the printed circuit Board corresponds to the reference.

 

On the PCB the drive is an eight-channel Phison controller PS5012-E12 with concomitant 512-megabyte chip DDR4-2400 SDRAM Hynix production required to store a working copy of the table of address translation. The array of the flash memory formed from four chips labelled TA7AG55AIV which are located on the front side of the Board as on the back. Such chips by order of the Phison company manufactures PTI, which procures semiconductor stuffing directly from Toshiba. End up in every chip flash memory, posted on the Gigabyte Aorus RGB M. 2 NVMe SSD is four 256-Gigabit crystal Toshiba TLC 3D NAND with 64 layers, but the cutting and sorting these crystals of semiconductor wafers in charge of the Taiwan intermediary.

Thus, it seems that the Gigabyte drive should be used semiconductor crystals of relatively good quality. Such a conclusion can be drawn from the stated high-resource SSD with a small volume of the reserve space. After formatting, the owner of a 512-Gigabyte drive will be available approximately 476 GB of storage, 36 GB is a SLC cache, so a replacement Fund is just nothing.

#Software

Today almost all SSD manufacturers offer a utility service that allows you to monitor the status and manage their SSD. Gigabyte this role is assigned to the SSD utility Tool Box, but from the point of view of functionality should be included among the worst examples of similar programs: it is not able to practically nothing.

The only thing you can do with this utility is to see General information about the SSD to access its S. M. A. R. T.-telemetry, and run Secure Erase. The interface also provides the Optimization tab, but to choose it is not available.

As follows from statistics that are eager to share key SSD manufacturers, the supply of the usual 2.5-inch SSD with SATA interface as a percentage is gradually decreasing, and come to the fore more advanced products with NVMe interface. Yet SATA hard drives hold the lead in sales, but, in the unanimous opinion, the change has to happen in the course of this year, and should facilitate this ongoing active reduction of prices on the NVMe model.

What NVMe drives are getting cheaper now much more active than a traditional SATA SSD, it is not surprising. Initially on high-speed products using the PCI Express bus architecture, manufacturers have established additional fees. Now, however, they have to give. As NVMe segment grows, it comes to an increasing number of players who do not want to lose its sphere of influence promising direction and are prepared to wage aggressive fight. However, the current situation is that the fight over the attention of buyers due to the speed or functionality of NVMe products today are capable of very few. Leading positions in consumer NVMe SSD in terms of speed and functionality firmly seized offers Samsung. As we have repeatedly seen in the tests, a couple of Samsung PRO 970 and the 970 EVO Plus demonstrates a very convincing superiority over any alternatives, and any large or small competitors of South Korean company failed to construct any similar performance decision. As a result, most firms have no choice but to try to attract users and to get involved in a fierce price war.

This, of course, plays into the hands of buyers. A characteristic feature of today was the fact that among the variety of NVMe SSD formed a significant number of proposals with prices more specific to models with the SATA interface. Simple example: right now the stores are just a few options NVME drives, which are cheaper than the popular SATA model 860 Samsung EVO. And among them not only based on QLC 3D NAND solution in the face of Intel SSD 660p and Crucial P1 — included in this list and SSD c three-dimensional TLC-memory, using both a cut-down PCI Express 3.0 x2 (for example, Kingston A1000 and its similarity on the basis of the controller Phison PS5008-E8) and a full-fledged PCI Express 3.0 x4 (for example, Transcend MTE110S and analogs on the controller SMI SM2263XT).

We try not to overlook this kind of budget, but not trimmed on architecture NVMe SSD, which promise is clearly the best combination of price and performance than SATA drives. Today we consider it necessary to draw attention to one very interesting product – ADATA XPG SX6000 Lite. This SSD is the cousin of the recently reviewed ADATA XPG SX6000 Prowhich produced a very good impression against other budget proposals with NVMe interface. But now ADATA a little dance with the configuration and offers about the same thing, but noticeable 15% cheaper. As it turned out — we just try to find out in this review. After all, if you believe the manufacturer, the new ADATA XPG Lite SX6000 does not change either the base controller or the type of flash memory. And if this is true, then we have a very attractive model that is extremely affordable NVMe SSD to PCIe 3.0 x4, based on TLC 3D NAND and obviously superior in speed, any SSD with SATA interface.

#Specifications

Speaking about ADATA XPG SX6000 Lite, we do often will do the references to XPG SX6000 Pro. The manufacturer does not deceive when he says that it’s close relatives. Both the drive are based on the same controller Realtek RTS5763DL and use the same three-dimensional 64-layer TLC 3D NAND second generation manufactured by Micron. Why ADATA has released two (almost) identical drive on a different price and how did she seriously throw off the price of the Lite model? The answer to these questions is very simple: the cheaper versions applied a cheaper memory, which, on the one hand, has a lower gradation in quality of semiconductor crystals, and with another – increased to 512 GB, the volume of the crystals. The first reduces the resource and the second performance. And here before us there SX6000 XPG Lite, at first glance, the same as the XPG SX6000 Pro, but really – is completely different.

However, if we talk about the architecture of the considered innovations, in the address XPG Lite SX6000 difficult to make any special claims. Moreover, at first glance, this drive is almost too good to be one of the most affordable NVMe SSD on the market. Although controller Realtek RTS5763DL that serves as its basis, is found in the mass drives are extremely rare, this chip is quite worthy to occupy this place.

In essence, the budget RTS5763DL indicates only one thing – he is deprived of the DRAM controller, which eliminates the feasibility of the drives on the basis of traditional buffering table of address translation. But it is supported by buffering non-traditional, technology-based HMB (Host Memory Buffer). This means that RTS5763DL in Windows operating system 10 is capable of use for their needs part of the normal RAM that is available to him through the DMA mode of the PCI Express bus. Regarding other features, the controller is quite typical: it has four channels to communicate with flash memory, supports LDPC coding for error correction and uses four lines PCI Express 3.0 to enable the system. In other words, it is quite possible to compare with the same SMI SM6263XT, which created a long NVMe SSD.

Nevertheless, do not forget: XPG SX6000 Lite developers saved on the flash memory. Increased to 512 GB size crystals 3D TLC NAND is not as scary as QLC, but nevertheless negative influence of this factor can be seen even in passport characteristics.

If we compare the characteristics of the ADATA XPG SX6000 Lite specifications with the XPG SX6000 Pro, it becomes immediately clear that the low cost of new items will be traceable in all aspects. Diminished even the declared speed that drives manufacturers usually try to inflate all possible ways, given the technology SLC-cache, and as deep pipelining of requests. Thus, performance in reading has lost 12-15 %, and the record is 17-20 %.

That performance has decreased due to the decreased degree of parallelism of the array of flash memory (this is caused by the transition to a more capacious crystals), it is easy to see and the reduction in the rates of direct entry to bypass the SLC cache. In order to clarify how the ADATA XPG SX6000 Lite technology works rapid entry, we carried out a standard experiment with a continuous filling of the 512-Gigabyte version of the SSD by sequential writing. The results can be seen in the graph below.

SLC-caching ADATA XPG SX6000 Lite works on a simple dynamic algorithm — on-the-record in high-speed mode uses all available free memory. Therefore, clean the drive in SLC mode, able to record about 170 GB (one-third of the total). Performance at SLC record reaches 1.2 GB/s but then it drops sharply to about 130 MB/s, and with a very strong scatter in the instant figures. For comparison, the speed of the array of flash memory XPG SX6000 Pro was 20-25% higher. This way is manifested the penalty associated with a halving of parallelism of the array of flash memory from a cheaper model of drive. In the result in order to fill the 512 GB version of the ADATA XPG SX6000 Lite completely, you need to spend about 45 minutes. And it is very long: for example, 970 Samsung EVO Plus a similar volume can be completely down in 10 minutes.

At the same time, it should be noted: dynamic caching is good because it maximally protects the user from seeing the true speed of the array of flash memory in TLC mode. If you leave the drive has enough free space, even a slow SSD like XPG SX6000 Lite will be able to provide acceptable write speed. However, there is another “but”. This drive doesn’t have its own DRAM buffer is used for buffering tables of address translation memory system, the speed of XPG SX6000 Lite when working with large volumes of data can be reduced even for this reason. As practice shows, a significant drop in the speed parameters from XPG SX6000 Lite (like XPG SX6000 Pro) occurs when random operations on files or groups of files larger than 4 GB.

In other words, we should not forget that the ADATA XPG SX6000 Lite is still a budget NVMe drive, and if you decide to save, you will have to put up with some features. Moreover, such compromise in this case is considerably greater than in the case of XPG SX6000 Pro. And it’s not only about performance. For example, a cheaper version of the SSD you’ll be the worst warranty and lower the declared resource of the flash memory. While for XPG SX6000 Pro warranty period is 5 years on the Lite version is only reduced to three years warranty, is not peculiar to drives with NVMe interface, including model on the base of QLC-memory. In addition, for SX6000 XPG Lite warranty may only 480 times overwrite the amount of drive, while the ADATA XPG SX6000 Pro during operation, you can completely overwrite 600 times. However, as we know, such requirements have a formal character and to practice have a rather distant relationship.

In fairness it should be noted: some ADATA XPG SX6000 Lite is still superior to the XPG version of SX6000 Pro. Lineup of this new product includes four representatives, and the minimum capacity of the SSD is only 128 GB. However, the performance of the younger of the modifications is at a very low level. The 128-Gigabyte model, where the array of flash memory runs in dual channel mode, is unlikely to please the owners of superiority over SATA SSDS. That is why capacity XPG SX6000 Pro began with a 256-Gigabyte mark.

#Appearance and internal structure

For testing we used a representative lineup ADATA XPG SX6000 Lite with a capacity of 512 GB. On the one hand, this version has the sufficient degree of parallelism of flash memory and promises good performance, and on the other is a little more than 5 thousand rubles.

First look at this SSD enough to understand that this is really a close relative of the XPG SX6000 Pro. As Pro memory, new XPG SX6000 Lite is a unilateral module in the form factor M. 2 2280 with a black PCB, but also equipped with the same set of components distributed across the Board is absolutely in the same way. Differs only in the range of chip flash memory, which on XPG SX6000 Lite 512 GB turned out to be two and not four, as on a more expensive SSD.

 

Actually, in this lies the main feature of XPG SX6000 Lite. If XPG SX6000 Pro used chips collected most of ADATA 256-Gigabit 64-layer semiconductor crystals TLC 3D NAND, purchased from Toshiba, now on-chip flash memory emblazoned marking SpecTek. And this is a clear sign, well describing the complexity of the drive, because SpecTek, a subsidiary of Micron, through which American manufacturer of semiconductors, so as not to tarnish his reputation, sells products with reduced quality grades. However, the TLC 3D NAND chips, which are mounted on XPG SX6000 Lite, belong to the category of Full Spec for SSD (100%), that is, they are pre-tested and still recognized by the manufacturer fit for use in SSDs.

Each chip flash memory contains within itself the four semiconductor crystal TLC 3D NAND with increased up to 512 GB capacity, and this means that the four-channel controller Realtek RTS5763DL in poltorabatko drive is able to use only a two-fold alternation of the devices in the channels. That is why the model number XPG SX6000 Lite performance with growth increases up to a maximum versions of the SSD capacity of 1 terabyte.

All circuitry ADATA XPG SX6000 Lite fits in three chips. In addition to the flash memory on the Board is a basic and controller Realtek and no more additions and are not required. On the Board are empty “landing pad” under additional chips flash memory, but they are utilized exclusively for the senior modification. Usual same chip dynamic memory here is not needed at all, because we consider the SSD relies on the unbuffered architecture and technology HMB.

Although XPG SX6000 Lite and is among the most affordable NVMe SSD, which finds a direct reflection in its hardware design, ADATA suddenly paid some attention to the heat sink. The SSD comes complete with aluminum heat distribution plate with an adhesive layer, which the user can optionally attach to the surface of the chip.

However, its small thickness and the sleek profile is unlikely to provide a high efficiency of heat dissipation, but even this option is still better than nothing.

#Software

With the service software from ADATA, the situation is far better. Proprietary tool for storage companies exist, but is it extremely sluggish, but its features and interface leave much to be desired. Moreover, a number of users who activated the zoom function of the interface in Windows, in General, she can not use.

However, the basic functionality utility ADATA SSD Toolbox still provides.

 

So, in addition to issuing full diagnostic information about SSD, ADATA SSD Toolbox allows you to inspect the flash memory drive, send him a package of TRIM commands, or perform the automatic adjustment of operating system settings (disabling Superfetch, Prefetch and Defrag).

 

Also using ADATA SSD Toolbox to upgrade the firmware and perform a Secure Erase procedure.

 

In addition, after registration, acquired XPG SX6000 Lite on the manufacturer’s website you can get the key to a popular program for cloning data Acronis True Image HD 2013/2015.

It just so happens that the manufacturers of SSDs, which until now has not got its own teams of controllers, but do not want to overlook the market for SSD enthusiasts, no particular choice today. Suitable option for them, allowing to organize the Assembly really productive drives with the NVMe interface that offers only one company is Silicon Motion, which is ready to deliver integrated solutions from your controller and firmware ready for everyone. Public base IC to build NVMe drives and there are other firms, for example, the same Phison or Realtek, but that Silicon Motion has taken the lead in this area, offering partners not only more functional, but much more fast acting solutions.

At the same time, among the huge variety of NVMe drives based on controllers Silicon Motion, of interest to enthusiasts can imagine not all models. This company produces a wide range of microchips with a fundamentally different level of performance, but performance worthy of an SSD for advanced or maximum configuration, can provide only selected platforms. In particular, last year we spoke about the controller SM2262: by the standards of 2018, he really looked very attractive, enabling drives based on it act on an equal footing with the best consumer NVMe SSD manufacturers of the first echelon, including Samsung, Western Digital and Intel.

But this year the situation has changed, as leading manufacturers have updated their mass top-level model. In response, Silicon Motion began to offer our partners an improved version of last year’s controller, SM2262EN, which also promises increase in performance – primarily in recording speed. It turns out, that storage devices based on this chip should be interested buyers who expect to get a more modern and fast NVMe drive, but do not want to overpay for the possession product A brand.

Until recently, the new controller SM2262EN used in their products is not so many manufacturers. In fact, the choice boiled down to two options: ADATA XPG SX8200 Pro and HP EX950. But now appeared the third storage device based on this chip – it has mastered the production of the company Transcend. With this new product, called Transcend MTE220S, we’re going to explore in this review.

Inputs to this familiarity are. HP EX950 not available in Russia, and ADATA XPG SX8200 Pro in our recent testing nothing trumps not demonstrated, suggesting that the performance of drives on the last controller SM2262. And this means that, despite the emergence of new versions of the Silicon Image controller, no NVMe SSD that would be able to compete with fresh 970 Samsung EVO Plus , we have not yet seen. Will Transcend MTE220S more interesting in comparison with ADATA XPG SX8200 Pro version, we are going to find out in this review. But it should be emphasized that, even if this SSD and not flash high-speed parameters, it can still be quite interesting. Because Transcend was going to sell it at a surprisingly low price — at least low for a full drive PCI Express 3.0 x4 DRAM buffer and a three-dimensional TLC-memory.

#Specifications

Details about what is a controller SM2262EN, we talked when you met ADATA XPG SX8200 Pro. On the technical side, this chip is built on two ARM Cortex cores, uses an eight-channel interface for controlling the flash memory has a DDR3/DDR4 interface for buffer and supports the bus PCI Express 3.0 x4 NVM Express Protocol 1.3. In other words, it is a modern and complete solution for NVMe drives, which also has a very good performance theoretical performance and supports advanced error correction techniques.

Initially, the controller SM2262EN was submitted in August of 2017, along with the “simple” SM2262, however, was presented as his “advanced” version, delivery of which was to begin later. Apparently, Silicon Motion was going to hold it up to the market introduction of the 96-layer TLC 3D NAND then to offer accelerated comprehensive solutions with a denser flash memory. However, this plan fell through due to changing market trends: NAND chips began to fall in price rapidly, and manufacturers of memory decided to delay the introduction of new technologies. The result is Silicon Motion got tired of waiting and released SM2262EN as an update to SM2262 as part of the platform, oriented to work with a 64-layer TLC 3D NAND.

In this case, according to the formal specifications, version platform controller SM2262EN still promises performance improvements of up to 9% sequential read, up to 58 % – sequential writes, up to 14 % – with random reads, and up to 40% at random writes. But if to believe these numbers with great caution. The developers say directly – no modifications in the hardware structure SM2262EN implies, it uses exactly the same architecture as conventional SM2262. All the benefit is based on changes in the software part: platform with a new controller uses more sophisticated algorithms to record and SLC-caching. In other words, we are talking about some attempt to cut corners, not that the engineers managed to make a breakthrough in the mechanisms work.

What this means in practice, we have seen, when tested ADATA XPG SX8200 Pro based controller SM2262EN. This drive was faster than its predecessor the chip SM2262 only in benchmarks, but offered no noticeable improvement in real performance. However, Transcend MTE220S the story is somewhat different. This drive has no close relatives in the lineup, and to Transcend this brand new model. In light of the fact that early in the lineup of this manufacturer was only NVMe SSD entry-level passport characteristics MTE220S look very impressive.

Interestingly, the claimed performance Transcend MTE220S slightly below those speeds promised for your similar drive based controller SM2262EN ADATA. Apparently this is due to the fact that although MTE220S and uses the same hardware and software platform, its design differs from the reference. For your drive, Transcend has designed its own printed circuit Board, where in order to reduce abandoned the use of 32-bit DRAM interface buffer in favor of more cost-effective, 16-bit connections. The result is lower top speed of random read and write, and this is especially noticeable in the version of the drive capacity of 512 GB.

However, SLC caching to Transcend MTE220S works exactly the same as other drives with the controller SM2262EN. The cache uses a dynamic scheme when one bit in a crash mode translates the part of the TLC memory from the underlying array. The cache size is chosen so that in the SLC-mode worked about half of the free flash memory. Thus, high speed MTE220S you can record the amount of data, the size of approximately a sixth of the available space on the SSD, then the speed will be significantly reduced.

This can be illustrated by the following graph, which shows how the performance of a continuous sequential write to blank Transcend MTE220S a capacity of 512 GB.

In accelerated mode, when the recording is performed in the SLC-mode, a 512-Gigabyte version MTE220S provides the performance level of 1.9 GB/s In TLC mode, the array of flash memory runs significantly slower, and after the exhaustion of free space in the SLC cache, the speed is reduced to 460 MB/s. On the chart is visible and the third option is speed – 275 Mbps. To the point performance when sequential write is reduced in the case when the free flash memory is longer, and in order to put some additional data the controller you first need to translate the cell is used for SLC-cache in normal TLC mode. The result is that the average speed of continuous recording on a Transcend 512 GB MTE220S “from the beginning to the end” is about 410 MB/s, and to fill up this drive data is necessary to spend at least 21 minutes. It is not too optimistic: for example, the same 970 Samsung EVO Plus you can completely clog the eyeballs in just 10 minutes.

While SLC-cache Transcend MTE220S characterized by the same unique feature we found in ADATA XPG SX8200 Pro. Data is transferred in conventional memory is not immediately, and only when it is filled more than three quarters. This allows to increase the speed of reading when referring to files that were recorded just. This option makes little sense in real-world use of the SSD, but it helps a lot to drive in synthetic benchmarks, which are practicing scenarios of the “record — reading”.

How this looks in practice can be assessed according to the following schedule speed random reads when accessing the file immediately after you created it when following this file in the SSD was recorded some amount of information.

Here very clearly seen the moment when the controller moves the test file from the SLC cache to the main flash memory, because the speed melkoplodnogo reading at this point drops about 10 %. With such a reduced speed and will have the business users in the vast majority of cases, since there are no reverse algorithms move data from TLC memory in the SLC cache in the firmware Transcend MTE220S not provided, and to stay in SLC-cache files just in case, if the drive is in the process of operation remains free more than 90 percent.

In other words, the work of SLC-cache Transcend MTE220S little different from other drives based on controller SM2262EN. But this does not mean that it is similar to ADATA XPG SX8200 Pro in all. The Transcend offers a significant advantage of a different order – a higher allowed by the terms of the guarantee the amounts of rewriting. Without loss of drive can be completely overwritten data 800 times, and the version of 256 GB is more than 1000 times. Such parameters of the declared resources allow to hope for MTE220S manufacturer of purchased the flash memory of the higher gradation of quality, and this means that the actual reliability of the drive can make even those users who still belong to TLC 3D NAND with a large grain of salt.

#Appearance and internal structure

For a detailed acquaintance by tradition the model has been chosen to Transcend MTE220S of 512 GB. No surprises its good looks, it is not presented, it is the usual storage form factor M. 2 2280, which operates via the bus PCI Express 3.0 x4, and supports the NVM Express Protocol version 1.3. However, the type of packaging and delivery MTE220S evoke stable Association with cheap consumer goods. Even budget UN-buffered SSD MTE110S the company sold in a full box, and the novelty is positioned as a solution to a higher level, were Packed in blister packs, in which, in addition to the M. 2 card storage, no nothing. This is all very reminiscent of the kind available on the market microSD card, and obviously serves the purpose of reducing overhead costs. However, hardly anyone still chooses SSD packing.

Not an impressive appearance and consider myself an SSD. In its design there are no radiators, and the sticker does not have a layer of heat-conducting foil. And in General Transcend MTE220S looks more like an OEM product, rather than as a solution for enthusiasts. Emphasizes this impression is PCB PCB is almost forgotten already green and purely utilitarian label, which has no signs of design, and contains only service information.

The layout of the Board MTE220S not be called model — it, apparently, Transcend the engineers have modified for their own needs. At least previously reviewed the ADATA XPG SX8200 Pro despite using the same hardware platform, looked quite different. However, the bilateral arrangement of the components of the new Transcend preserved, therefore, for “low profile” slots M. 2, which occur in thin laptops, MTE220S may not be suitable.

 

An array of flash memory located on MTE220S 512GB scored four chips with their own marking Transcend. Know that within each of these circuits is four 256-Gigabit crystal 64-ply Micron memory TLC 3D NAND second generation. Transcend buys such a memory from Toshiba in the form of solid plates, but cutting, testing and packaging of silicon chips in the chip takes over, which allows to achieve additional production savings.

Attention should be paid and a chip DDR4-1866 SDRAM, next to the chip base controller SM2262EN. It serves as a buffer to store a copy of the table of address translation, but it is important here that in the drive there is only one such chip, manufactured by Samsung, with a capacity of 512 MB. We specially pay attention to it, as other SSD controller SM2262EN fast DRAM buffer typically consists of a pair of chips less than half volume. As a result, Transcend MTE220S work with DRAM buffer occurs via a 16-bit, not 32-bit bus, which in theory can hurt performance when melkoplodnyj operations. However, the influence of this factor should not be overestimated: a 32-bit bus for the RAM is a unique feature of the platform SM2262/SM2262EN, while the other controllers to use SSD DRAM buffer with 16-bit bus and absolutely do not suffer from this.

#Software

For service drives its own production the company produces special utility Transcend SSD Scope. It’s almost typical for software of this class, but some familiar features for some reason are not supported.

 

SSD Scope allows you to monitor the overall status of your drive and assess his health, referring to the telemetry S. M. A. R. T. utility available, simple tests of speed and also check the firmware version and its updates.

 

Also, the utility includes a tool to clone the contents of disks, which enables quick and painless to transfer the operating system and installed applications on freshly bought SSD. Plus, the SSD Scope is able to control the transmission to the drive the TRIM command.

 

For SATA SSD Scope may also offer validation of the array of flash memory for errors or performing a procedure “reliable cleaning” flash memory Secure Erase. But with Transcend MTE220S both of these functions for some reason do not work.
