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.

Random Read Performance

The drive powers through the read part of the test without displaying any problems. The drive's performance increasing smoothly as the queue depth deepens.

Random Write Performance

In the write tests, testing with one thread sees the drive peak at 91,539 IOPS at a queue depth of 2 before slipping back to finish the test at 90,849 IOPS. With 2, 3 and 4 threads the initial burst of performance peaks for all at the QD4 mark with the rate of increase slowing from QD4 to QD8.
