HP FX900 Pro 2TB SSD Review

We used CrystalDiskMark 8’s custom settings to test the 4K 70/30 mixed read/write performance of the drive through a range of queue depths using a single thread and four threads.

The HP FX900 has no problem dealing with our 70/30 read/write tests either with a single thread or four threads. With a single thread, the drive climbs from 25,696 IOPS (105.23MB/s) at QD1 up to 107,956 IOPS (442.18MB/s) at QD8 before dropping back to finish the test run at 107,700 IOPS (441/13MB/s) at QD32.

With four threads the drive goes from 99,622 IOPS (408.05MB/s) at QD1 up to 325,157 IOPS (1,331.84MB/s) at QD32 but the rate of increase slows from QD8 onwards.
