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
As with our 4-threaded random 4K read testing, we couldn't get close to the official rating of 1,200,000 IOPS in our random write tests. The best we saw was 245,619 IOPS (1,006MB/s) at QD32.
