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.

Using four threads in our 70/30 read/write tests, the performance of the 4TB NM790 ranges from 100,025 IOPS (409.704MB/s) at QD1 to 575,081 IOPS (2,355MB/s) at QD32 where the performance rate of increase starts to slow down. Switching over to a single thread the performance runs from 23,905 IOPS (97.91MB/s) at QD1 up to 221,288 IOPS (906.39MB/s) at QD32.
