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 C910 as up to 615,000 IOPS. With our four threaded tests, we couldn't get close to this, the best we saw from the drive was 317,299 IOPS (1,299.66MB/s) at QD16. From QD8 until the end of the test at QD32 the write performance plateau's off.

4K Random Write v QD performance compared.

The CRAS C910 sits in a mid-table position at QD1 and moves up the table in QD2 but from QD4 onwards it slowly drops down the table.
