We used CrystalDiskMark 8 to test the random performance of the drive at lower queue depths (QD1 – QD8 where most of the everyday workloads occur) using 1 to 4 threads.

4K Random Read Performance QD1-QD8

In our lower queue depth, 4K random read tests, the performance increases steadily as the queue depth deepens for each thread. At QD1 the performance ranged from a low point of 18,572 IOPS (76.07MB/s) for a single thread up to 73,781 IOPS (302.30MB/s) for four threads. At QD8 a single thread produced 121,044 IOPS (495.79MB/s) and four threads, 345,030 IOPS (1,413.24MB/s).

4K Random Write Performance QD1-QD8:

In the 4K write test both one and two-thread performance begins to slow from QD2 onwards while using three and four threads sees the slow down happening from QD4.
