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.
The best result we saw from our 4K random write results was even further away from the official maximum IOPS figure (2,600,000 IOPS) than the random reads. The drive peaked in this test at QD8 with a test figure of 461,228 IOPS before gradually dropping back to finish the test run at QD32 with a figure of 455,551 IOPS.
4K Random Write v QD performance comparison.
The best performance from the drive came at QD1 where it sits in fourth place.
