Crystal Disk Mark 3.0 is in the spotlight. We will be switching to Crystal Disk Mark 6.0 soon, but for the sake of consistent comparison, we will stick with this version for this review. Just a bit of background information; higher capacity drives tend to perform a little better in these tests. The ability of a controller and flash memory to deliver high IOPS will provide huge benefits to the score as well. The Western Digital Black NVMe SSD 1TB is rated at up to a whopping 500,000 IOPS read and 400,000 IOPS write. Looking at the read and write results of all four sections, the Black NVMe was the undisputed winner in the sequential and 512K write tests, but fell to second place in the 4K write test and third in 4K QD32. When it came to read, the story was a little different. It came in second in the sequential, 512K, and 4K QD32 tests, but bombed it in the 4K read test. I will let you make your own comparisons in our list of SSDs in the graphs above.
