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.

PNY doesn't put any random performance figures on any specification sheets we have seen for comparison with our test results. The best figure we saw in our 4-threaded testing was 357,730 IOPS (QD32). Between QDs 8 and 16, the performance appears to dip slightly before recovering well.

4K Random Read v QD performance compared.

In comparison to the drives around it, the CS3140 performs best at QD2. At a QD of 32, the drive has slipped back down towards the bottom of the chart.
