We used CrystalDiskMark 8‘s custom settings to test the 4K random read 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.

WD rate the 1TB Blue SN580 at up to 600,000 IOPS for 4K random reads. With our 4-threaded test, we were unable to reach this figure, our test producing a maximum of 454,815 IOPS. The drive climbs steadily through the tested queue depths till the end of the test run.

4K Random Read v QD compared.

We may not have been able to match WD's maximum 4K random read rating for the drive, but it still produces an impressive feat by being the fastest 1TB class Gen 4 drive we've seen at QD32.
