We used CrystalDiskMark 8‘s custom settings to test the 4K random write performance of the drive through a range of queue depths. The setup for the tests is listed below.

Transfer Request Size: 4KB, Outstanding I/O: 1-32.

Klevv rates the 4K random write performance of the 2TB Cras C925 as up to 100,000,000 IOPS. With our four threaded tests, we couldn't get close to this, the best we saw from the drive was 337,936 IOPS (QD32).

4K Random Write v QD Performance Compared

The random write performance of the drive sees in the bottom third of the table at QD1, dropping down to the penultimate position at QD2 before staging a recovery at QD4, with the drive climbing up the chart to finally sit in a mid-table position at QD32.
