About Crystal Disk Mark

- Peak/Real World Performance Profile

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. The ADATA Legend 960 1TB is rated at up to 730,000 IOPS read and up to 610,000 IOPS write, which is very good. 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.
ADATA claims the Legend 960 1TB's maximum read and maximum write are pinned at 7400MB/s and 6000MB/s, respectively. Looking at the read and write results, the Legend 960 1TB was one of the fastest drives, if not the fastest drive, in the sequential read and write sections against other PCIe 4.0 NVMe drives. Its tested write speeds were simply untouchable, and the tested read speeds were at or near the top of the charts. The tested Seq1M Q8T1 read speed was bang on compared to the specifications, while the Seq1M Q8T1 write speed was about 10% faster than advertised.
In the RND4K Q32T1 tests, the Legend 960 1TB proved to be significantly faster than the XPG Gammix S70 Blade 1TB. However, it barely beat the budget Crucial P3 Plus 1TB, and significantly behind the also budget WD_BLACK SN770 NVMe SSD 1TB and flagship Kingston FURY Renegade 1TB. Lastly, in the RND4K Q1T1 segment, we see pretty much the same pattern. I will let you make your own comparisons in our list of NVMe SSDs in the graphs above.
