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 a single thread, the performance climbs from 36,965 IOPS (151.35MB/s) at QD1 to 208,701 IOPS (854.83MB/s) at QD32. Using four threads, the performance slowly rose from 136,150 IOPS (557.67MB/s) at QD1 to 164,997 IOPS (675.82MB/s) at QD2 but from that point the drive accelerated up to a peak of 588,870 IOPS (2,412.01MB/s) before dropping back to 546,150 IOPS (2,310.76MB/s) at the end of the test run at QD32.
