We used CrystalDiskMark 8‘s custom settings to test the 4K random read performance of the drive through a range of queue depths. The setup for the tests is listed below.
Transfer Request Size: 4KB, Outstanding I/O: 1-32.
With our 4-threaded random 4K read testing we couldn't get close to the official rating of 1,00,000 IOPS with a best test result of 374,849 IOPS at QD16.
4K Random Read v QD compared.
At QD1, 2 and 4 the 2TB Crucial P310 sits in a mid-table position, however, by QD32 it has dropped down the chart.
