Evaluation| Western Digital WD Black NVMe SSD

by editor · March 30, 2019

With the development of 3D NAND flash technology and the popularity of the M.2 interface, the high-speed, compact, wiring-free M.2 SSD has become one of the hottest products on the market. The recent sharp drop in price of memory and SSD is the best time to buy M.2 SSD. Recently, the Western Digital WD Black NVMe SSD are released , let us take a look about it’s 3400MB / s read speed.

Unpacking and appearance introduction

Western Digital WD Black NVMe SSD’s outer packaging continues the previous succinct, black and white box and the sticker on the disc perfectly echoes, the top is the official name of the product, the following is a brief description of the product model and capacity information, using 3D NAND flash granules with a read speed of up to 3400MB/s and a five-year warranty. The WD Black NVMe SSD is available in 250GB, 512GB, and 1TB capacities. We tested the 500GB version this time.

Western Digital WD Black NVMe SSD is the brand’s highest-order black disk. In order to mark the black disk, it also brushes its PCB board into black, and the gold interface echoes the black PCB board, which enhances the visual effect inside the chassis. The SSD is a standard M.2 2280 specification that supports the NVMe protocol and is optimized for BiCS flash to provide enhanced performance using its own new Flash Master.

This 500GB SSD uses a single-sided particle design. One is to show the manufacturer’s powerful hardware design capability and integration. The other is to make the memory particles and circuit components only on one side, which is more conducive to heat dissipation. Rate, from the details of the work can be seen in the front line of the big factory.

Performance test: 3400MB / s makes the computer performance more violent

In the official promotion, the 500GB version of the WD Black NVMe SSD has a sequential read speed of 3400MB/s and a sequential write speed of 2500MB/s. This speed is impressive, and whether it can achieve such a level. , detailed performance testing will be carried out immediately.

Western Digital WD Black NVMe SSD uses the M.2 2280 specification, compatible with mainstream Intel and AMD platforms, ready to use, no installation difficulty.

In the test, we use the Windows 10 64-bit version of the operating system, turn off all Windows boot items, turn off the write buffer refresh and ASPM power management, do not optimize the operating system, only to obtain the most authentic original objective evaluation data. Provide the basis. Test software is the most common and intuitive CrystalDiskMark, ATTO Disk Benchmark.

Through the CrystalDiskMark test, we can see that the WD Black NVMe SSD has a continuous read speed of 3400MB/s and a continuous write speed of 2539MB/s, which exceeds the nominal 3400MB/s and 2500MB/s read/write speed. . The 4K data random read and write performance is also close to 1000MB/s, and the test results are satisfactory.

Continue to use ATTO Disk Benchmark for testing. This is an easy-to-use disk transfer rate detection software that can customize the test packet size. Here, 0.5KB, 1KB, 2KB is selected until the 8192KB packet is read and written. Can better simulate the actual use.

The test results are shown in the figure. It can be seen that when using a file test of 64 KB or less, the SSD read/write performance is not fully utilized. The maximum write speed is 1937 MB/s, and the read speed is even slower than the write speed, which is 1380 MB/ s. When the test file size is increased to 1024KB-8192KB, the write speed is basically stable at 2535MB/s and the read speed is 3365MB/s.

Continue to switch to 512B, 1KB, 2KB until 64MB packets are read and written respectively, the maximum write speed is also 2.42GB / s, the read speed is 3.21GB / s, enough to see its performance.

Evaluation summary: high speed、stable、 low power consumption

WD BLACK NVMe SSD is the highest-end SSD in Western Digital history. Its performance is undoubted. The 3400MB/s, 2539MB/s read/write performance, 300TBW ultra-high endurance and 5-year warranty also prove the strength of the big manufacturers. For e-sports players, hardware enthusiasts, editors and other users, this should be a product that you won’t give up after you experience it. At present, the 500GB capacity WD BLACK NVMe SSD e-commerce is priced at 899 yuan, it is worth starting.
