We used CrystalDiskMark 8‘s custom settings to test the 4K random write performance of the drive through a range of queue depths

In the random 4K 4-treaded write test, the drive's performance peaked at 373,802 IOPS (1,531.09MB/s) at a QD of 16 before dropping back slightly to finish the test at 371,677 IOPS (1,522.39MB/s).

4K Random Write v QD performance compared.

Unlike the 4K random read performance, when it comes to random writes the drive is at the top of the charts for all tested queue depths, with the exception of QD2 where Samsung's SSD 980 PRO still reigns supreme.
