PNY XLR8 CS3040 1TB SSD Review

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.

4K Sustained Random Read

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 420,899 IOPS (QD32).

4K Sustained Random Read IOPS v QD compared.

In comparison to the drives around it, the XLR8 CS3040 performs best at QD32 where it sits in third place behind WD's Black SN850 and the 2TB version of Sabrent's Rocket 4 Plus.
