Lexar Professional NM800 Pro Heatsink 2TB SSD Review

We used CrystalDiskMark 8 to test the random performance of the drive at lower queue depths (QD1 – QD8 where most of the everyday workloads occur) using 1 to 4 threads.

Random Read

Using a single thread the performance of the Lexar Professional NM800 Pro Heatsink ranges from a low point of 21,364 IOPS at QD1 up to 121,984IOPS at QD8. The progression between QD1 and QD8 is a pretty smooth one. Using four threads the drive climbs from a low point of 84,604 IOPS up to 353,705 IOPS.

Random Write

When it comes to 4K random writes, each thread tested peaked at QD2 before the performance seemed to plateau out.
