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 C925G as up to 1,000,000 IOPS. With our four threaded tests, we couldn't get close to this; the best we saw from the drive was 495,124 IOPS (QD16) before sinking back to 494,085 IOPS at QD32.

4K Random Write v QD Performance

At QD1, the performance of the drive sees it in the lower half of the results chart. But as the QD deepens, the drive moves up the results chart into eighth place at QD2, fourth place at QD4, before dropping down to fifth place at QD32.
