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.
Using our 4-threaded random read 4K tests, we couldn't get close to the official maximum of 2,200,000 IOPS. The best test result was 519,939 IOPS at a queue depth of 16 before the performance backed off a little to finish the test run at 518,452 IOPS (QD32).
Even though our 4K random read test results were nowhere close to the official maximum figure at any stage, the drive sits in the top spot at QD1, 2 and 4, by quite a margin. However, at QD32, it has slipped down the chart, ending up in sixth place.
