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 MP700 Elite with Heatsink produced results that ranged from 27,795 IOPS (113.85MB/s) at QD1 up to a peak of 176,537 IOPS (723.09MB/s) at QD16 before dropping back a little to finish the test run at QD32 at 176,109 IOPS (721.34MB/s).
Switching up to four threads the performance goes from 108,721 IOPS (445.32MB/s) at QD1 to a peak of 500,841 IOPS (2,051.44MB/s) at QD16 before dropping back to 499,359 IOPS (2,045.38MB/s) at QD32.
