CrystalDiskMark is a useful benchmark to measure the theoretical performance levels of hard drives and SSDs. We are using v8.0.
The CRAS C925 read score of 82.3MB/s in CrystalDiskMark 8's 4K QD1 test sees it in the middle of the pack sitting in between the Seagate FireCuda 530 and Corsair's MP600 PRO XT. Its write performance in this test is a little disappointing as both the previously mentioned drives have better write figures.
A glance at the benchmark result screens shows that using the default test the drive came up a little short of the official maximums of 7,400MB/s and 6,500MB/s for Sequential reads and writes respectively. Although switching over to the compressible data test we could confirm the official read figure but the write performance dropped some 400MB/s.
The CRAS C925 Sequential read test result of 7,347MB/s puts the drive into a lower mid position in the results chart.
Peak Performance Profile
The drive is officially rated at 700,000 IOPS for random reads and using the Peak Performance profile of CrystalDiskMark8 we got a nice increase on the official rating at 853,261 IOPS. However, it was a different story for the random write test, the best we saw was 607,320 IOPS, way off the official 1M IOPS figure.
As with the default test, we couldn't confirm the official maximums for Sequential performance for either reads or writes.
Real World Profile
In the Real World profiles test the drive's Sequential read result of 4,544MB/s sees it slip into the top ten in the results chart. Its write performance however is somewhat stronger at 5,406.28MB/s.
