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.

The Samsung 990 Pro has no Problem dealing with our 70/30 read/write tests either with a single thread or four threads. With a single thread, the drive climbs from 24,159.3 IOPS (98.95MB/s) at QD1 up to 111,139 IOPS (455.22MB/s) at QD32.

With four threads the drive goes from 95,179 IOPS (389.57MB/s) at QD1 up to 324,330 IOPS (1,328MB/s) at QD32 but the rate of increase slows from QD8 onwards for both threads.
