We used CrystalDiskMark 8‘s custom settings to test the 4K random read 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.

Officially, the 2TB CRAS C925G is rated as up to 700,000 IOPS for 4K random reads. With our four-threaded tests, we couldn't get close to the official maximum figure with a peak test result of 603,572 IOPS at QD16 before the performance dropped back to 601,330 IOPS at the end of the test run (QD32).

4K Random Read v QD performance

Although we couldn't get close to the official 4K random read figure, it is a consistent drive, as the test results we did get saw the drive in the top ten results for all the tested queue depths. Compared to the drives around it, the drive's slowest performance came at QD1, with the fastest at queue depths 4 and 32.
