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 Crucial T700 performance climbs in a fairly smooth curve from 26,920 IOPS (110MB/s) at QD1 up to 168,114 IOPS (688MB/s) at QD8 where the performance slowly begins to plateau out, finishing the test run (QD32) at 179.918 IOPS (736MB/s). Using four threads the performance climbs from 108,994 IOPS (446MB/s) at QD1 to 502,947 IOPS at QD16 before slowly flattening out, finishing the test run at 503,716 IOPS (2,063MB/s).
