CrystalDiskMark is a useful benchmark to measure theoretical performance levels of hard drives and SSD’s. We are using v6.0. and v8.0
The PNY XLR8 CS3040 scores in CrystalDiskMark 6 see the drive placed in the middle of the results chart. Comparing the two CrystalDiskMark result screens shows that the Phison E16 controller that the XLR8 CS3040 uses is much more efficient when reading compressible sequential and 4K data at certain queue depths. We could also confirm the official maximum Sequential read figure of 5,600MB/s with a test result of 5,640MB/s. The write result of 4,273MB/s is a little shy of the official maximum of 4,300MB/s.

CrystalDiskMark 8 Real World Performance Profile
CrystalDiskMark 8 comes with a couple of interesting ready-made testing profiles as well as a dedicated NVMe setting. The best tested sequential figures for reads, 5,620MB/s confirms the official maximum figure while the best Sequential write test result of 4,279MB/s is a little shy of the official maximum of 4,300MB/s.
The best tested random 4K figures in CDM8 for the drive are 658,325.68 IOPS for reads and 546,826.17 IOPS for writes. Unfortunately, we couldn’t confirm how these figures match up to the official ones as PNY don’t have the random performance figures featured on any specification sheet for the drive we’ve seen.
