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 the four threaded 4K 70/30 read/write tests, the performance of the 4TB Corsair MP700 PRO SE ranges from 103,949 IOPS (425MB/s) at QD1 to 504,764 IOPS (2,062MB/s) at QD32. With a single thread, the test results range from 26,767 IOPS (109.64MB/s) at QD1 up to 176,132 IOPS (721.439MB/s) at QD32.
