About Crystal Disk Mark

- Measure Sequential and Random Performance (Read/Write/Mix)
- Peak/Real World Performance Profile

From: Developer's Page




Crystal Disk Mark 8.0 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. As manufacturer peak read and write performance ratings are usually achievable using Crystal Disk Mark, whether a drive lives up to its marketing claims or not can be validated by this program.

Western Digital claims the WD_BLACK SN770M 2TB's maximum read and maximum write are pinned at 5150MB/s and 4850MB/s, respectively. Looking at the read and write results, the SN770M 2TB was about mid-tier in the sequential read and write sections against other PCIe 4.0 NVMe drives, but this was to be expected per the specifications. The tested numbers were pretty close compared to the advertised numbers. It continued to perform reasonably well for its performance class, staying just behind the SN770 and delivering significantly better results than the Lexar PLAY in every test except for the RND4K Q1T1 test. Overall, the WD_BLACK SN770M 2TB punches strongly for a compact budget performance SSD. I will let you make your own comparisons in our list of NVMe SSDs in the graphs above.
