CrystalDiskMark is a useful benchmark to measure theoretical performance levels of hard drives and SSDs. We are using v8.0.5.

The CRAS C925G read score of 73.53MB/s in CrystalDiskMark 8's 4K QD1 is 8.77MB/s slower than the CRAS C925, but its write performance has improved from 234.43MB/s to 252.49MB/s, representing an increase of 18MB/s.

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 378MB/s.

The CRAS C925G Sequential read test result of 7,352 MB/s places the drive in 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 993.696 IOPS. We could confirm the official random performance of 1M IOPS with a test result of 1,024,788 IOPS.

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 4,231MB/s sees it slip into the top ten in the results chart. Its write performance, however, is somewhat stronger at 5,345MB/s.
