HP FX900 Pro 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 Reads

In our lower queue depth, 4K random read tests, the performance increases steadily as the queue depth deepens for each thread. At QD1 the performance ranged from a low point of 21,414 IOPS (87.71MB/s) for a single thread up to 122,348 IOPS (501.13MB/s) for four threads. At QD8 a single thread produced 84,867 IOPS (347MB/s), two threads 163,809 IOPS (670MB/s), three threads 289,006 IOPs (1,183MB/s) and finally with four threads, 353,567 IOPS (1,448MB/s).

Random Write

The FX900 Pro's write performance climbs smoothly throughout the tested queue depths with QD's 2, 3 and 4 closely matched.
