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.

With our 4-threaded random write tests, the best result we saw from the drive was 281,205 IOPS at QD16, with the performance dropping back to 280,801 IOPS at the end of the test at QD32, both figures nowhere near the official maximum rating of 450,000 IOPS.

4K Random Write v QD Performance compared:

The best performance from the drive in comparison with its competitors came at QD2 where the drive sat in a mid-table position.
