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

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 17,048 IOPS (69.82MB/s) for a single thread up to 65,171 IOPS (266.94MB/s) for four threads. At QD8 a single thread produced 109,514 IOPS (448MB/s), two threads 157,492 IOPS (645MB/s), three threads 245,569 IOPs (1,006MB/s) and finally with four threads, 288,643 IOPS (1,182MB/s).

4K Random Write

In the 4K write performance test it's only when using three threads that the drive's performance continues to climb through the tested queue depths. The three other tested threads see the performance begin to plateau out. With a single thread, it's at QD2, with two and four threads it's at QD4.
