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.

In the random write test, the best test result we saw from the Exceria Pro was 324,741 IOPS (QD16), which is nowhere near the official maximum of 1.3M IOPS. We did a quick test of the drive using eight threads at QD32 and got a test result of 417,058 IOPS, still nowhere close to the official figure.

4K Random Write v QD performance compared.

The drive performs reasonably well at QD1, sitting just outside the top five drives we've tested to date but at QD2 the drive plummets down the table. QD4 sees the drive's performance recover enough to place in the top ten but at QD32 it has slid down the table again, but nowhere near as dramatically as the QD2 drop.
