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 C910 produced results from 21,195 IOPS (86.81MB/s) at QD1 up to 117,747 IOPS (482.289MB/s) at QD32. However, from QD8 the performance began to plateau.
Switching up to four threads the performance climbs steadily from 81,599 IOPS (334.232MB/s) at QD1 up to 346,012 IOPS (1,417MB/s) at QD32.
