WD Black PCIe NVMe SSD Review (512GB) – Does It Live Up To Its Lineage?

HDTUNE

HD Tune is a Hard Disk Utility with many functions from error checking, health testing (S.M.A.R.T.), and of course benchmarking. To build upon our real world write test we also looked to see where the write speeds leveled off to by using HD Tune Pro. If SLC caching is being utilized, this test will typically show it.

WD BLACK PCIE HDTune

Finally, to end our bombardment of testing, we put the WD Black PCIe through HDTune’s write test. The results show that after the SLC buffer is full, speeds drop to about 350MB/s on average with some dips along the way.

REPORT ANALYSIS AND FINAL THOUGHTS

As we have demonstrated in testing today, the WD Black was able to achieve its performance ratings. It hit 2,050MB/s in sequential read and 800MB/s in sequential write. During our testing with HDTune, however, we could see that its 800MB/s performance can degrade to about 350MB/s due to WD’s utilization of TLC NAND and SLC caching algorithms rather than MLC NAND. 4K random performance was just about in line with the 170K/134K IOPS ratings and at QD1 it achieved very respectable numbers at just about 50MB/s read and 170MB/s write.

WD Black PCIe SSD

In PCMark 8 the WD Black PCIe achieved an average bandwidth of 357MB/s, which is better than any SATA SSD we have tested yet but is down on the low end of the scale for a PCIe SSD option. In PCMark 8’s extended test, we can see that there is a clear distinction between the MLC and TLC NVMe PCIe SSDs such as this one, except in the case of the Samsung 960 EVO. Samsung always seems to be sprinkling magic into their 3D TLC…

Finally, during our real-world file transfer, we saw that the WD Black PCIe’s TLC NAND and SLC caching wasn’t enough for our 30GB of test files. It ranked low on our charts and proved to be inefficient during writes. It did, however, beat most of the other SSDs when comparing idle power consumption.

FINAL THOUGHTS

Overall, it outperforms the Intel 600P, but not by much. With the WD Black PCIe at its current prices of $109.99 (256GB) and $199.99 (512GB), the Intel may be a better buy for someone looking to get the cheapest NVMe SSD they can get their hands on or if they are looking for something in a 1TB flavor. Just as well, looking at drives priced the same or similarly to the WD Black, it is hard to ignore the MyDigitalSSD BPX. It is a much better buy.

This is not to say the WD Black PCIe is a bad SSD, because it is not. It has decent performance and has a few pros, such as a single-sided PCB design, which means it is compatible with more laptops/portable devices. WD also allows you to use Acronis True Image WD Edition Software for cloning and backup, download their WD SSD Dashboard to monitor the SSD, and it comes with a 5-year warranty, which you just can’t go wrong with.

We just feel the WD Black PCIe SSD does not quite live up to its lineage. It has an identity crisis. Yes, it is their fastest drive and it is much faster than any SATA SSD out, but it is not quite the best they could do, nor is it competitive with the many other high-end PCIe SSDs. Sure, WD said it wasn’t meant to compete in the high-end segment, but the WD Black line has traditionally contained some of the fastest mainstream HDDs over the years. Selling a Black labeled NVMe PCIe SSD with TLC NAND as an entry level NVMe PCIe option in the market seems absurd! We would go as far as to say that this SSD should have been labeled as a WD Blue PCIe. Then, later, release a WD Black PCIe with MLC NAND. The PCB is even blue! They totally missed out on developing a true WD Black PCIe SSD with a blacked-out PCB and top ranking performance with MLC NAND! But I digress, that is beside the point. Let’s get back on track.

Would we recommend this SSD? Yes. For the reasons mentioned above, it is not the best SSD out, but it will be more than adequate for its intended audience. Thus, we are awarding the WD Black PCIe our Recommended Award! If the WD Black PCIe catches your eye and you are ready to buy, be sure to…

WD Black hard drives have long been the go-to hard drive for many storage consumers. They satisfy the needs of those looking for fast, reliable storage and although they are priced on the high side, they come with a 5-year warranty, which is hard to beat. However, with the release of so many SSDs into the market, WD had been falling behind. Consumers now demand faster storage than what HDDs can offer. WD had no choice but to finally enter the SSD market. Due to this, WD acquired SanDisk, which in turn gave them the necessary tools to make their entrance. After some months…

Is it really a WD Black?

The WD Black PCIe NVMe M.2 SSD is a decent mainstream offering. The marketplace is tough with fierce competition, however. The available cloning software and SSD dashboard are both great to have for end users, as well as the 5-year warranty, but we feel the WD Black PCIe is going to have a hard time standing out. It delivers the rated performance of 2GB/s read and 800MB/s write, but that write speed can drop off to about 350MB/s on average once the SLC cache is filled. Overall, it is very close in performance to the Intel 600P, although slightly better. There are better values in the market that you may want to consider before buying this SSD, but it isn't the end of the world if you blindly chose this one....it still performs better than SATA.

    Wd very late to the ssd market, still finding their feet. Average drive, but 5yr warranty is standout feature.

    • Yeah they are. Their first PCIe option is fairly good, I can’t wait to see what the next version has in store now that they got their feet wet.
