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.
From QD4 up to QD32 the performance of the drive levels out, with a peak of 328,531 IOPS at QD16 before dropping back a little to finish the test run at 326,497 IOPS. As with the random read results, these are nowhere near the official 1,000,000 IOPS maximum write figure.
4K Random Write v QD compared.
The drive performs best, in terms of our results charts at QD1 where it sits in fifth place. At QD2 the drive is very nearly sitting in last place but stages a recovery in QD's 4 and 32.
