Western Digital Black 3D NVMe SSD: High-end performance at near entry-level prices - gentryselead

At a Peek

Expert's Rating

Pros

• Superlative-notch execution
• Priced more like a budget NVMe SSD than a bounty manikin
• Five-class warranty

Cons

• Drilling recording label
• Easy to confuse with an elder WD Black SSD that was too M.2/NVMe

Our Verdict

The Western Integer Shameful 3D NVMe SSD is as fast as Samsung's 960 Pro, but it costs a lot fewer. In fact, IT's only slimly more expensive than entry-level drives. It's the drive that smart buyers should choke for.

Western Digital's WD Black 3D NVMe SSD delivers often the same performance as the chart-top-flight Samsung 960 Pro, but for significantly less cash—$200 to a lesser extent in the 1TB capacity.

This is a good thing, and a big cheese. Samsung has been accepted in the death-user, performance NVMe SSD market since its inception. If you wanted best speed at a fairly reasonable price, the company's SSDs were your just selection. Until at once.

Note of hand: This revaluation is part of our primo SSDs roundup. Go there for details about competing products and how we tested them.

Intent and spectacles

Announced Thursday, the WD Black 3D NVMe is an M.2, PCIe x4 SSD in the 2280 (22 millimeters wide, 80 millimetre long) conformation factor. It uses WD's 3D TLC NAND, though WD was unable to confirm the number of layers. The NAND resides on just one side of the PC board, sol the Total darkness 3D NVMe lav consort the marginal confines of thin-profile laptops.

The Black 3D NVMe has roughly a 1GB/1MB NAND-to-DRAM-cache ratio, then you get 256MB of DRAM with the $120, 250GB drive, 512MB with the $230, 500GB drive, and 1GB with the $450, 1TB capacity. WD wouldn't talk about the measure of NAND being utilized in SLC modality (piece of writing only one bit) as a secondary cache, but we're assuming it's somewhere around the traditional 1.5 to 2.5 percent of total capacity.

WD

WD's Black 3D NVMe SSD. Finally there's competition for the Samsung 960 Pro. Much more affordable challenger.

The WD Black 3D NVMe is covered away a five-year warranty and rated for  200TBW (TeraBytes Left-slanting) for the 250GB capacity, 300TBW for the 500GB capacity, and 600TBW for the 1TB capacity. All but users won't touch those amounts in 10 years of continuous manipulation.

Note of hand:In that respect is already a WD Afro-American SSD connected the market in the M.2/PCIe 2280 form factor. This is not that drive. If it doesn't say "WD Non-white NVMe" on the label, information technology's the experient drive.

Performance

In most respects, the WD Black 3D NVMe closely coordinated operating room exceeded the 960 Pro's performance. However, it fell low-set happening one and only OR two tests, well-nig notably non-queued sequential recitation (raw sustained throughput) with CrystalDiskMark 5, and a mysteriously slow random write access time in AS SSD 1.9. The last mentioned disables caching, so information technology's non indicative of a drive's real-world performance.

CrystalDiskMark had nice things to say active the WD Black NVMe, rating it as the better author, though the 960 In favor of was the slightly better reader when multiple files were queued for writing.

IDG

The WD Black more than held its personal in CDM 5 with queues live.

The numbers pool below are quite different, informatory US that WD's caching techniques are quite effective when queues are involved.

IDG

The story was different, turning out in much the Samsung 960 Pro's party favour without writes being queued. That is, one file cabinet at a meter fed to the drive. . Fortunately for the Clad NVMe queues are nearly e'er in period of play with NVMe.

When queues weren't involved (see supra), as when a single generous file is copied, the Samsung 960 Pro was rated as quite bit quicker by CDM 5. AS SSD 1.9, seen below cerebration the different, placing the WD Black in front. Go figure.

IDG

Sustained performance in A SSD was an overall win for the WD Sarcastic NVMe.

Only with the FUA command incapacitating write caching, something that never happens in the ending-exploiter surround, the WD Black's smaller writes fell off the planet. To be fair, this is much the same phenomenon we saw with Samsung's own 950 Pro noncurrent in the daylight. Caching is a requirement for these drives to keep up with the speed of the bus.

IDG

4K performance fell with a vengeance in favor of the Samsung 960 Pro. AS SSD 1.9 turns off drop a line caching, but the 960 may have unnoticed that.

Because on that point's so much disparity in the synthetic benchmarks we've been using (we've already started moving our quiz MO towards the more modern and homogenous Eastern Samoa SSD 2.0 and CDM 6), we tend to trust our 20GB file replicate tests more when IT comes to sustained throughput. Here, the WD Black 3D NVMe was very good with our 20GB mathematical group of files and folders, but not quite as tight as the Samsung 960 Pro with the solitary large 20GB file. We also Federal Reserve System the drive 48GB data sets from our new test layout without whatsoever appreciable slowdown complete the integral copy.

IDG

When it came to our real-world 20GB copy well-tried, the Sandisk Extreme Pro was extremely hurrying with files and folders, merely not as fast as the 960 Pro with large files. However, this chart besides shows just how fast even a budget NVMe effort so much as the Plextor M9Pe canful be.

Notice that you'll get somewhat slower ordered spell performance impermissible of the 500GB Black 3D NVMe. Approximately 300MBps slower, according to WD. The Black 3D NVMe 250GB suffers a major cliff in indite performance of 1.2GBs. It's relieve a fast screw the grand scheme of things, simply that's a major difference of opinion. Eminence that Samsung's 960 In favor doesn't non suffer a dropoff in the 512GB capacity (and International Relations and Security Network't gettable in a 256GB version).

Buying advice

You get much the same performance with the Western Digital Black 3D NVMe as you perform with the Samsung 960 Pro, merely for the price of a slower Samsung 960 EVO. In fact, it costs simply a teensy more than the launching-level Plextor MP9e we compared it to in the performance plane section. That makes the WD Black 3D NVMe by far the sweetest sell in the performance NVMe market right now.
