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

TSSDR TEST BENCH AND PROTOCOL

SSD testing at TSSDR differs slightly, depending on whether we are looking at consumer or enterprise SSDs. For consumer SSDs, our goal is to test in a system that has been optimized with our SSD Optimization Guide. To see the best performance possible, the CPU C states have been disabled, C1E support has been disabled, Enhanced Intel SpeedStep Technology (EIST) has been disabled. Benchmarks for consumer testing are also benchmarks with a fresh drive so, not only can we verify that manufacturer specifications are in line but also, so the consumer can replicate our tests to confirm that they have an SSD that is top-notch. We even provide links to most of the benchmarks used in the report.

SYSTEM COMPONENTS

This Test Bench build was the result of some great relationships and purchase; our appreciation goes to those who jumped in specifically to help the cause. Key contributors to this build are our friends at ASRock for the motherboard and CPU and be quiet! for the PSU and cooling fans. Also, a big thank you to Thermaltake for the case and Kingston for the RAM. We have detailed all components in the table below and they are all linked should you wish to make a duplicate of our system as so many seem to do, or check out the price of any single component. As always, we appreciate your support in any purchase through our links!

BENCHMARK SOFTWARE

The software in use for today’s analysis is typical of many of our reviews and consists of Crystal Disk Info, TRIMcheck, ATTO Disk Benchmark, Crystal Disk Mark, AS SSD, Anvil’s Storage Utilities, HDTune, and PCMark 8. We prefer to test with easily accessible software that the consumer can obtain, and in many cases, we even provide links. Our selection of software allows each to build on the last and to provide validation to results already obtained.

CRYSTAL DISK INFO VER. 6.8.2

Crystal Disk Info is a great tool for displaying the characteristics and health of storage devices. It displays everything from temperatures, the number of hours the device has been powered, and even to the extent of informing you of the firmware of the device.

WD BLACK PCIE CDI

In Crystal Disk Info, we can see that SMART is supported and there are quite a few useful metrics one can monitor, including total host reads and writes, temperature, and more. The firmware we are testing today is B35200WD.

TRIMCHECK

We’ve covered TRIMcheck in the past. It is a great tool that easily lets us see if TRIM is actually functioning on a SSD volume in your system.

TRIMcheck Working

As can be seen in the screenshot above, TRIMcheck’s result is positive. TRIM is indeed working.

ATTO DISK BENCHMARK VER. 3.05

ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 8192kb. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.

WD BLACK PCIE ATTO

Our first look at the WD Black PCIe’s performance shows some rather low results. Performance at the smaller file sizes is much lower than that of any other PCIe SSD or SATA SSD we have tested as of late. It reaches its rated read speed at the 256KB file size and rated write speed at the 16KB file size. At the end of the test the performance drops off to under 1GB/s at the 48MB and 64MB file sizes.

  • Dromo

    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.
