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 (2,200,000 IOPS) than the random reads at 476,761 IOPS (QD16). The drive finished the test run at 473,101 IOPS (QD32).
At QD1, the drive sits close to the bottom of the chart, but as the tested queue depths deepen, the performance improves, placing the drive in the top five for all the remaining tested queue depths.
