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 Reads.
In the random read tests, all four of the tested threads displayed smooth increases in performance as the queue depth deepened with no nasty surprises.
Random Writes.
In the 4K write tests the performance rose quickly from QD1 to QD2 for all four tested threads before levelling off for the rest of the test runs.
