We used CrystalDiskMark 8 to test the random performance of the drive at lower queue depths (QD1 – QD8 where most of the everyday workloads occur) using 1 to 4 threads.

4K Random Read

The 1TB Crucial P5 Plus read performance climbs smoothly throughout the tested queue depths and threads with a peak performance figure of 344,454 IOPS (1,410MB/s) at QD8 using 4 threads.

4K Random Write

Using one and two threads, the drive peaks at QD8 (137,562 IOPS and 88,374 IOPS respectively). However, using three and four threads the drive peaks at QD4 before slipping back slightly at QD8.
