We used CrystalDiskMark 8’s custom settings to test the 4K 70/30 mixed read/write performance of the drive through a range of queue depths using a single thread and four threads.
In our 4K 70/30 tests using a single thread, the 2TB CRAS C925 produced results from 22,344 IOPS (91.52MB/s) at QD1 up to 139,770 IOPS (572.49MB/s) at QD32. Switching up to four threads the performance goes from 87,287 IOPS (357.52MB/s) at QD1 up to 382,335 IOPS (1,566.04 MB/s) at QD32.
