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 P5 Plus doesn't seem to handle the single-threaded CrystalDiskMark QD32 test very well at all, sitting as it does at the bottom of the results chart. On the other hand, we could confirm the official Sequential read/write figures for the drive of up to 6600MB/s and 5,000MB/s for read and rights respectively with test results of 6,607MB/s for reads and 5,018MB/s for writes.

Looking at the two benchmark result screens it appears that the Micron controller the drive uses doesn't care about the type of data it's being asked to handle.

CrystalDiskMark 8 Peak Performance Profile

CrystalDiskMark 8 Real World Profile


CrystalDiskMark 8 comes with a couple of interesting ready-made testing profiles as well as a dedicated NVMe setting. The best tested Sequential figure for reads, 6,853.07MB/s once again confirms the official rating, as does the best write result of 5,021.18MB/s.

The best tested random 4K read figure in CDM8's Peak Performance was 622,561.52 IOPS a little short of the official maximum of 630,000 IOPS. The best write figure of 497,361 IOPS was well short of the official maximum of 700,000 IOPS.
