We also 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.
Between QDs 1 and 2 using a single thread, the drive's performance climbs slowly from 11,655 IOPS (47MB/s) to 13,164 IOPS (60MB/s). After QD2 the performance climbs sharply until the end of the test run (QD8) with a final test figure of 58,999 IOPS.
Using 2, 3 and 4 threads the drive produced figures of 61,570 IOPS (252MB/s), 73,785 IOPS (302MB/s) and 75,667 IOPS (309MB/s) respectively at a QD of 8.
In the write tests, the drive peaks at QD4 (67,245 IOPS) using a single thread before falling back slightly to finish the test run 67,185 IOPS. When tested using 2, 3 and 4-threads there is a marked difference in performance at QD1 but by QD4 the performance of the threads is very much closer with the spread of results going from the slowest 67,245 IOPS (2 threads) to 71,721 IOPS (4 threads), a trend that continues to the end of the test run.
