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 four threads in our 70/30 read/write tests, the performance of the 2TB Crucial T500 ranges from 97,191 IOPS (398.09MB/s) at QD1 to 487,219 IOPS (1,995MB/s) at QD32. With a single thread, the performance ranges from 24,840 IOPS (101.74 MB/s) at QD1 up to 171,611 IOPS (702.917MB/s) at QD32.
