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 the 4K random read tests, the random write test results are well short of the official 2.4M IOPS, peaking at 545,055 IOPS (QD16) before dropping back to finish the test run at 521,573 IOPS.

4K Random Write v QD compared

At QD1, the 2TB WD_Black SN8100 sits in fourth place on the results table. At QDs 2 and 4, the drive has slipped to sixth place. But by QD32, it has moved up to the top spot with a test result of 521,573 IOPS.
