SSD Drive WD Green Reviews. WD Green SSD drive - turn on the turbo on the old computer. New SSD WD Green and WD Blue - Budget and Middle Class

Popular SSD-discs of the American company in the Russian market Western Digital. Proven to be reliable, high-quality and productive drives. Line of solid-state storage devices are divided into a series, allowing you to easily find a suitable drive for specific requirements and tasks.

WD Black - Quick SSDs desktop computers and PC with a small form factor. The drives of this series with the TLC memory are made in the form factor M.2 2280 and support M.2 PCI-Express interface, providing a lightning transmission. The sequential reading speed reaches 2050 MB / s, and records up to 800 MB / s. Such characteristics provide maximum speed when performing complex tasks. The average time of operational failure (MTTF) at 1.75 million hours provides long-term reliability of 512 GB drives and 256 GB.

WD BLUE - reliable solid-state drives for personal computers and laptops with 3D TLC memory. High resource up to 400 TB for recording operations and 1.75 million hours of average time for failure provide data protection on the disks of this series for many years. Such drives are available in the M.2 2280 and 2.5 inches form factor with M.2 SATA and SATA 6GB / S interface, respectively. These light, compact and productive SSD discs with a capacity of 250 GB, 500 GB and 1 TB support Trim and show excellent read speed and write data - up to 560 MB / s and 530 MB / s.

WD Green - economical SSD discs for the upgrade PC and laptops. With the drives of this series, watching web pages, games and starting the system will occur in the blink of an eye. They use TLC and 3D TLC Memory and the Silicon Motion controller supporting SATA 6GB / S and M.2 SATA interface. Mutnified in the form factor M.2 2280 and 2.5 inches These discs provide high speed reading and write information - 540 MB / s and 465 MB / s, respectively. These light and shock-resistant solid-state drives do not contain moving parts, thanks to which the data loss does not threaten even if the SSD has hit or drop. Disks with a capacity of 240 GB and 120 GB support Trim, and their resource reaches 80 TBW.

Undoubtedly, one of the most significant IT industry events in 2016 was the acquisition of the Western Digital company SanDisk - a major manufacturer of storage devices based on flash memory. This profitable deal not only ensured the presence of WD on the market of solid-state drives and memory cards, but also gave access to SanDisk assets, including joint C TOSHIBA production of NAND chips, on which active preparations are already being prepared for the supply of multilayer 3D NAND on an industrial scale. Thus, the prospects of the Alliance Western Digital and SanDisk look very promising and the first fruits of this union can be considered the SSD output under the Western Digital brand. Currently, the vendor is represented by the ruler of solid-state drives Green and Blue. Green SSD is positioned as inexpensive universal entry-level solutions, while the "blue" series devices are intended for more wealthy users who have increased requirements for the speed of the disk subsystem. Who knows, perhaps in the future, we will see the BLACK ruler drives for enthusiasts or specialized modifications Red for data storage systems. Thanks to the efforts of the Ukrainian representation Western Digital, the Green PC SSD 240GB and Blue PC SSD 250GB and Blue PC SSD 250GB are included in our test laboratory, with a detailed overview of which we are today and introducing.

The current range of WD solid-state drives has only five positions, the main characteristics of which are shown in the following table.

It should be noted here that each model can have one of two constructive versions: in the 2.5 "housing" or M.2 2280 format. With regard to the range, there are only two modifications of 120 and 240 GB in the "green" ruler, whereas "Blue" drives are offered in three dimensions: 250, 500 and 1000 GB. Traditionally, the higher the capacity - the higher the speed indicators and the resource, whereas the average time of operation for the refusal of 1.75 million hours is equally for all devices, no longer differs warranty service - 36 months from the date of purchase. Regardless of the form factor, all solid-state drives are compatible with the SATA 6 Gb / s interface.

We went to the tests of the eldest of two "green" SSDs, namely WDS240G1G0A, which arrived in the test laboratory in retail packaging decorated in white and green colors. All the details, including the name of the model, its volume, production date and serial number of the device are applied to the sticker located on the back of the box.

As for the supply kit, it is actually absent: inside the package there is nothing in addition to the drive, wrapped in an anti-static package and laid in a plastic blister, so I propose to immediately move to the design of the novelties. The SSD body is entirely made of plastic, which provides a small mass of the product - just 32 g. The dimensions are typical for the form factor 2.5 "- 7x69,85x100.5 mm. This is good when using the drive in thin laptops, but when installing, the laptop will not prevent the frame that increases the height to 9 mm in the standard compartment.

Most of the reverse side of WD Green PC SSD 240GB is engaged with a sticker with service information. One of the SSD ends is given under the SATA 6 Gb / s interface, combined with the power connector. By the way, the maximum power consumption of the drive in read and record mode does not exceed 2 and 2.5 W, respectively, whereas the mean value is about 0.05 W.

Inside the housing, the halves of which are connected without screws using a number of latches, there is a miniature printed circuit board, which is hardly 1/3 of the total utility area. By the way, the inscription SanDisk on the RSV turquoise color issues the true origin of the solid-state drive. On the front surface there was a pair of SanDisk 05498 064g chip, which is based on 15-nm TLC NAND semiconductor crystals made at a joint venture Toshiba and WD (SanDisk).

On the reverse side of the printed circuit board there are two more such flash memory chip and SM2258XT microcontroller manufactured by SiliconMotion. This chip, optimized to work with the TLC NAND flash memory, is designed to build inexpensive energy-efficient drives of both user and industrial classes. SM2258XT Provides a four-channel connection of 16 TLC storage devices and 3D NANDs with Onfi 3.0 and Toggle 2.0 interfaces, the Trim command and DevSLP power control hardware control are supported. To ensure the integrity of the data, a special cyclic code is applied with NANDXTEND error correction, and the only thing that distinguishes this microcontroller from more advanced solutions is the lack of hardware encryption. However, with the lack of the latter, it is possible to come true if we take into account the positioning of the device. SSD works under the firmware of the Z3311000 firmware - the last version available at the time of testing.

Four chips TLC NAND with a capacity of 64 GB each give a total volume of 256 GB, from which the user is available to 240 GB, and the remaining place is used to align the non-uniformity of the cell wear. In addition, in the WD Green PC SSD 240GB storage, a small part of the total disk space It can work in SLC mode, due to which the speed in the recording operations is noticeably rises, which is usually a "weak place" for TLC flash memory. Judging by the testimony in the AIDA64 Disk Benchmark test, the size of such "SLC buffer" depends on the nature of the load: with a continuous recording, within the first 4-5 GB, the speed is about 450 MB / s, after which the average speed is set at 147 MB \u200b\u200b/ s, which can be considered a very decent result as for SSD initial price range. With a random record of blocks in size 4K, the drive allows you to record about a quarter of volume with a stable speed at 130 MB / s, after which the average productivity rate is reduced to 107 MB / s, but failures of up to 30 MB / s happen. However, in real conditions, this nature of the load is found not often, besides the drive, it takes quite a bit of time to rebuild data and prepare a "SLC buffer" to record the next portion of the data.

Thus, WD Green PC SSD 240GB is a typical representative of inexpensive SSDs based on TLC NAND with all its features of operation. As for reliability, the manufacturer has established a resource of the storage device at 80 TBW, which means daily overwriting to 1/3 of the drive for a 3-year warranty period.

Despite the formal affiliation to more high class The box of solid-state drive "Blue" series is nothing but a color scheme, does not differ from WD Green PC SSD 240GB. Packaging design is also concise: on the reverse side the most the necessary informationAnd the delivery kit is as as ascetic.

As for the design of the device itself, in contrast to the younger model, the top cover of the housing is made of aluminum alloy. At the same time, the form factor 2.5 "and the size of 7x69,85x100,5 remained the same, while the mass of the drive increased slightly - only 5.4 g to 37.4 g.

The facial SSD surface is occupied by a colorful sticker, and back cover The whole is given under the sticker with official information. Under it are four screws with heads under the cross slot, fastening the halves of the case, so disassemble the devices without losing a guarantee, most likely will not come out. WD Blue PC SSD 250GB is equipped with a SATA 6 Gb / s interface, in read mode, it consumes 2.35 W, while the power consumption increases to 3.4 W.

After opening the case, the structure of the novice becomes visible. As with the WD Green PC SSD 240GB product, all components fit into small pCB The same azure color, on which SanDisk inscription is proud of. The base of the drive is the Marvell 88SS1074 microcontroller, which is in contact with the metal top cover through the thermal interface layer. The control chip has four channels for connecting MLC / TLC flash memory and 3D NAND with Toggle Mode 2.0 and Onfi 3.0 interfaces, and, maximum amount Storage devices reaches eight pieces on the channel. The controller supports low-level DEVSLP power management and hardware encryption with the AES-256 algorithm, and the LDPC code is responsible for the integrity of the data and error correction. To store the address translation table, the DDR3-1600 SDRAM SDRAM microcircuit is 256 MB. In addition, two SanDisk 05478 064g chip is located on the front surface of the RSV of 64 GB each, inside of which is 15-nm TLC NAND production TOSHIBA.

On the back of the RSV, two more TLC NAND chips with a capacity of 64 GB are installed, thus, the total flash memory of the novice is 256 GB, and 250 GB are available to users. Despite the fact that less than 2.5% of the total capacity, for Blue PC SSD 250GB, the vendor declares the impressive resource - 100 TBW for Blue PC SSD 250GB, which allows you to overwrite the contents of the drive at least 400 times!

As for compensation for a low TLC flash memory recording speed, then, as in the case of WD Green PC SSD 240GB, part of the cells work in SLC mode. According to the results of the AIDA64 Disk Benchmark test in linear operations, the first 5 GB drive is able to record with a maximum speed of 504 MB / s, after which the speed level decreases to 197 MB / s, whereas with a random record of blocks in size 4k performance remains relatively stable within the entire disk Spaces, than strikingly different from the model "Green" series. However, the SLC buffer's work algorithm can be changed with the output of the control firmware updates, so that the above described only the firmware version of the X41000WD.

As an intermediate result, it can be noted that, judging by the possibilities hardware WD Blue PC SSD 250GB will be able to take a worthy place among the drives of a similar class. As far as these hopes are justified - we will learn quite soon, after familiarization with the company software WD SSD Dashboard.

Software

One of the strong competitive advantage Western Digital solid-state drives is the presence of a powerful software Product SSD Dashboard, with which you can solve many tasks for maintaining and operating storage devices. At all, this program There is free access, but all the possibilities naturally are available only for systems equipped with WD products. According to the proposed capabilities of SSD Dashboard, it is in leads among similar software, perhaps, perhaps only Samsung Magician, which still can be considered a reference functionality. The utility interface is concise and pleasant, deprived of alappost, which many vendors are sinning from Asia. At the top of the window, the name of the drive model and the firmware version, as well as the status of the storage device, are displayed, whereas in the lower right corner there are buttons for calling system functions "Disk Management", "System Properties" and "Device Manager". On the Status tab, the user can control the use and marking of the disk space, obtain information about the quantitative indicator of the device status and its temperature, as well as the interface mode.

The "Execution" tab allows you to familiarize yourself with performance indicators, for this you need to activate the "System Monitor" built into Windows. This tool allows you to track the actual speed with great accuracy when performing various tasks.

In addition to monitoring productivity, the "Execution" tab allows you to manage the TRIM command, which serves to return the speed of the drive to the initial state. Users can activate or forcibly submit this command, as well as schedule its periodic execution using the OS function "System Planner".

The "Service" section, as follows from the name, is responsible for servicing the drive. Here you can check for firmware updates on the support server or specify the path to the local file with the firmware, create boot USB drive To execute Secure Erase and Sanitize procedures. Both procedures are aimed at guaranteed data destruction on SSD, only in the first case the table is removed with the markup, and in the second there is a complete erasing of the data.

On the Service tab, users can run fast and extended tests S.A.A.R.T. To determine the status of the drive, as well as view the current internal monitoring indicators. It also shows comprehensive information about a storage device and brief information about the system configuration.

And finally, the "Settings" menu is responsible for checking the updates of the application itself, select the interface language, as well as the alert settings on email or via SMS, for example, with new versions of firmware or troubleshooting in SSD.

Thus, the WD SSD Dashboard program offers a complete set of tools for monitoring and maintaining solid-state drives, which makes it possible to refuse to use third-party utilities, except for the case of data migration to a new drive.

Test results

Our today's testing opens CrystalDiskmark 5.2.0 x64 program, which allows you to evaluate the speed of drives when working with various types of data

In linear read operations, all drives demonstrate equally high results lying at the upper bandwidth boundary sATA interface 6 Gb / s. As for working with blocks 4K, when the query queue is generated in outsiders, WD Green PC SSD was obviously an absence. buffer memory SDRAM. With random reading, the best results came from WD Blue PC SSD, which went around even Kingston Ssdnow UV400, and the third place was divided by GEIL and WD "Green" series.

Since the CRYSTALDISKMARK settings selected 1 GIB test data, which is fully fits in "SLC-buffers" of storage devices, the results in the test tests turned out to be very high. When forming a queue of commands in the outsider, WD Green PC SSD was again, while his more advanced fellow took the first place, and in linear operations the third place was divided by the drives based on Silicon Motion controllers. As for the recording of the blocks of 4K, the query queue processing is better than all of the Kingston Ssdnow UV400, the WD Blue PC SSD is located with a minimum margin, and his younger counter again closed the four contestants. At the same time, in operations by chance that the blocks of blocks 4k, the difference between the leader and the outsider did not exceed 5%, so that we can talk about the approximate parity.

Another synthetic test optimized for testing solid-state drives - AS SSD BENCHMARK 1.9.5986.35387, showed such results.

In the subtraction of linear reading, the last place unexpectedly went to the WD-Blue series drive, whereas in three other disciplines he took the honored first. As for the results of WD Green PC SSD, he has nothing to boast, especially when measuring the access time.

A completely different situation in the recording pages, where the "green" model WD was decent, taking third place in scenarios that operate blocks 4k, but again installed an anti-record when assessing access time. As for WD Blue PC SSD, he looked much more confidently, in two disciplines, dividing the victory with Kingston Ssdnow UV400, and demonstrated the advantage in the subtest of random recording.

In addition to measuring the bandwidth AS SSD BENCHMARK allows you to measure the speed of copying different file sets.

When copying large files, all drives, with the exception of WD Green PC SSD, who managed to laggard behind the rest of the participants by 10%, showed more or less than the same speed, whereas when you move the folder with the pedestal set by the drive GEIL Zenith R3, it was located behind it. Green »Western Digital, and the SSD peloton is closed on the basis of Marvell controllers. In the Copying Personal Folder, the Kingston SSDNOW UV400 turned out to be the best folder, the WD Green PC SSD and WD Blue PC SSD are located, the firmware of which requires optimization when working with a mixed load.

Completes our testing the speed assessment in Storage Test from the comprehensive Benchmarck Futuremark PCMark. First of all, we suggest a look at the integral indicator of productivity and the average throughputSupported contestants.

Despite the fact that the scatter on the points between the leader and the outsider did not reach 4%, the difference in speed turned out to be very significant. And now, let's see what provided WD Blue PC SSD confident victory, and what was not enough WD Green PC SSD for a worthy rivalry with classmates.

As they say, comments are free: In most disciplines, the "blue" WD demonstrated the overwhelming superiority over rivals, but his younger fellow is as confidently settled down at the bottom of the tournament table. There is nothing to add here, programmers need to work on the firmware WD Green PC SSD to increase its speed.

conclusions

Considering that at this stage, Western Digital brought to the market under its brand well-known SanDisk solid storage devices, the debut could not fail. It was especially successful in the case of C WD Blue PC SSD 250GB, which provides excellent speed in most disciplines, has a worthy resource and at the same time offers the cost of 1 GB of disk space at the level of 0.36 dollars. If you add to this excellent software support and a 3-year warranty from the famous manufacturer, then it turns out a good candidate for purchasing as a main disk to the "charged" laptop or productive PC.

As for the younger model WD Green PC SSD 240GB, then it is not so unequivocal with it. On the one hand, the drive provides a speed that will be sufficiently overwhelming most users, especially in the case of a transition from a traditional HDD, slightly smaller than that of the "blue" SSD, resource, powerful software support and a 36-month warranty, but on the other hand, Its cost looks unreasonably high. With a ratio of $ 0.34 per 1 GB, it is advisable to draw up the eyes towards the same WD Blue PC SSD 250GB, which is able to provide much greater speed and even a little more volume. In general, that WD Green PC SSD 240GB become a bestseller, you need to either significantly tighten productivity by optimizing the firmware, or reconsider its retail price in a smaller side.

At the end of 2016, Western Digital Corp. (WDC) entered the market of solid-state drives with two rules - WD Blue and WD Green. Last year's SSD was not a breakthrough, but simply filled the gap in model row well-known manufacturer of drives. Of course, WDC decided not to dwell on it, and continued to develop a new direction for himself.

The result of her work we saw in the spring of 2017, when the announcement of the WD Blue line update was held, which received new memory with vertical laying cells (3D NAND). At the same time, the controller remained unchanged - this is the four-channel Marvell 88SS1074 chip. Drives will be supplied in two different formats (2.5 inches and M.2 2280) and with four variations in volume. The new type of memory allowed to increase the volume of up to 2 TB even in conditions of compact format M.2 2280. Let us estimate the rest of their capabilities and high-speed potential.

Packaging and equipment

The drive comes in a small cardboard box in the branded colors of the WD Blue line. The front side marked a three-year warranty, as well as the amount of memory. The reverse side is assigned to a sticker with service information and a small description of WDC Linek.

The WD Blue (WDS250G2B0B) model is securely fixed in a plastic form designed to protect it from mechanical damage during the transportation process.

Appearance of the device and its features

The SSD drive is made on a blue circuit board in M.2 2280 format. It has a one-sided layout. All chips are closed with a sticker with the name of the manufacturer, serial number Devices, as well as marks about the passage of various specifications. In turn, the reverse side of the board is completely devoid of any elements.

The controller is the four-channel Marvell 88SS1074 chip, which supports the following technologies:

NCQ (Native Command Queuing) - Hardware Setup Sequence, which allows you to optimize the performance of the drive;
S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) - monitoring system, following the condition of the drive, due to which it is possible to predict the time of its failure;
DeVSLP - allows you to completely disable the power of the SATA interface, allowing you to save more energy than the used partial power failure or sleep methods (Slumber), which implies the continuation of the physical level power;
Trim - allows you to directly delete data stored in flash memory and immediately release an unused place (free blocks) to use it to record information by the system.

As for memory chips, four microcircuits with "SanDisk 05138 064g" marking are used in the storage. Each of them is 64 GB, which results in 264 GB. At the same time, 14 GB are used under internal system algorithms.

Cache memory is implemented on the basis of the DDR3 chip chip Nanya NT5CC128M16IP-DI with a volume of 2 Gbps.

SSD is supplied formatted in file System NTFS. Its effective container is 249.9 GB or 232 Plex.

Testing

For testing, the next stand was used:

Motherboard	ASUS Prime Z270-A (Intel Z270, Socket LGA1151, DDR4, ATX)
CPU	Intel Core i7-7700K (Socket LGA1151, 4.5 GHz, L3 8 MB)

RAM	2 x 8 GB DDR4-2400 Hyperx Fury. HX424C15FBK2 / 16.
Video card	ASUS. GeForce GTX. 980 4GB GDDR5 Matrix Platinum
HDD	WD Purple (WD10PURX), 1 TB
Power Supply	Seasonic X-660 GOLD (SS-660KM Active PF), 650 W, 120 mm Fan
Operating system	Microsoft Windows 10 64-bit

When working with compressible data in the ATTO Disk Benchmark benchmark, high maximum results were recorded - 567 MB / s when reading and 525 MB / s.

The speed of reading and writing data with a volume of 4 KB in Atto Disk Benchmark is located on a very worthy level, a little advanced indicators of last year's WD Blue SSD. Recall that what they are higher, the faster the OS and application applications will work.

As for CrystalDiskmark, then in it we received almost identical to those in Atto Disk Benchmark results: 564 and 536 MB / s for reading and writing, respectively. The indicators declared by the manufacturer are 550 and 525 MB / s.

AS SSD BENCHMARK, like CrystalDiskmark, evaluates work with incompressible data. He showed 518 and 137 MB / s when reading and writing. The read speed turned out to be higher than that of the predecessor, but with an estimate of the recording speed of the Benchmark, the obvious problems that we are not previously observed.

In general, high-speed WD Blue (WDS250G2B0B) cannot be called recorded when compared with competitive 2.5 "drives. Nevertheless, the drive demonstrates a worthy level of performance and low data access delays. It will perfectly fit into a compact laptop or mini-PC, providing the user to the user a fairly fast and capacious storage.

Support for SLC-caching technology officially for this model is not declared. However, in the tests of HD TUNE PRO 5.60 and AIDA64 on the record of all available volume, we see that at first the speed reaches 280 - 350 MB / s, but after recording approximately 10 GB, it falls in the range of 200 - 215 MB / s. Recall that in cheaper models after falling the speed can reach 60-80 MB / s, so WD Blue (WDS250G2B0B) looks worthy of their background.

According to the indications of the built-in sensor, the accumulator temperature was about 56 ° C. The air temperature in the test laboratory did not exceed 25 ° C.

Softwaresecurity

The WD SSD Dashboard software can boast not only a pleasant design, but also excellent features that are to monitor the status of the drive, updating the firmware version, the performance diagnostics, which remains the resource, temperature and other parameters. Also present the possibility of forced cleaning the drive without subsequent recovery of data and passing S.M.A.R.T. Dough in fast and ordinary modes.

conclusions

Let's summarize the consideration of a compact SSD-drive of 250 GB. First, it is made in the popularity of M.2 2280 format, so suitable for ultrabooks or mini-pcs, in which it simply does not provide a place for a 2.5-inch model. But if you wish, it can be used in ordinary desktops or laptops equipped with the appropriate interface. Secondly, it uses the 3D NAND microcircuits, thanks to which the total volume (up to 2 TB) managed to increase and increase reliability indicators. In particular, the resource of the test model is 100 TB.

High-speed indicators are very ambiguous. On the one hand, in Atto Disk Benchmark and CrystalDiskmark, we see more than 500 MB / s to read and write data, and on the other - in complex tests And other benchmarks the device loses selected competitors. But in general, the indicators are very decent, especially if we are talking Transition from HDD on SSD. Reasoned and relatively high data recording speed with long load, which remained at the level of 200 - 215 MB / s, while at models with SLC caching technology it drops to 60-80 MB / s.

These discs are all the famous SanDisk, which I bought WD.
Confuses one thing that lately SanDisk has changed a lot of controllers, and by the way there are MARVEL lovers, so SanDisk has left them. By the way the controller is the same as in the AMD.
How they write that even the plastic body is the same
Going out of tests, who needs speed pay.
There are no discs for marriage no, I will unsubscribe.
