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
Using a single thread the 4K random read performance of the 2TB version of the MP600 GS ranges from a low point of 19,105 IOPS (78MB/s) at QD1 up to 120,814 IOPS (494MB/s) at QD8. With four threads the performance of the drive climbs from 74,910IOPS (306MB/s) at QD1 to 312,006 IOPS (1,278MB/s) at QD8.
Random Write
After the initial rise in performance between QDs 1 and 2, the write performance of the 2TB MP600 GS seems to plateau out across the remaining tested queue depths, regardless of the number of threads.
