Crystal Disk Mark 6.0 is in the spotlight. 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 SN750 NVMe SSD 1TB is rated at up to a whopping 515,000 IOPS read and 560,000 IOPS write. Looking at the read and write results of all four sections, the Black SN750 was the undisputed winner in the sequential and 4KiB Q8T8 write tests, but fell to second place in the 4KiB Q32T1 write test and only marginally edged out the last place Black NVMe in the 4KiB Q1T1 write test. When it came to read, the story was a little different. It came in first in the sequential, 4KiB Q8T8, and 4KiB Q32T1 tests while coming in second in the 4KiB Q1T1 test. I will let you make your own comparisons in our list of SSDs in the graphs above.
