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.
In our 4K random read tests, we could confirm the maximum official rating of 225,000 IOPS with a test result of 226,160 IOPS (926.353MB/s) at QD32.
4K Random Read v QD Performance compared.
At QD1 the P41 Plus sits in the top 10 of the results chart but as the tested queue depth deepens the drive drops down the chart until at QD32 it sits in last place on the chart.
