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 Write

Transfer Request Size: 4KB, Outstanding I/O: 1-32.

In the random 4K 4-treaded write test, the drive’s performance peaked at 362,946 IOPS (1,486MB/s) at a QD of 16 before dropping back slightly to finish the test at 362,693 IOPS (1,485MB/s).

4K Sustained Random Write IOPS v QD compared.

When it comes to 4K random write performance the XLR8 CS3040 sits in the top half of the results chart throughout all the tested queue depths with the best performance in relation to its competitors coming at QD4 where it sits in second place behind Samsung's SSD980 PRO drive.
