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.
Transfer Request Size: 4KB, Outstanding I/O: 1-32.
HP rate the 4K random read performance of the 2TB FX900 Pro as up to 1,344K IOPS. Using our 4-threaded 4K random testing, the best we saw was 358,138 IOPS (QD16).
4K Random Read v QD performance compared.
Even though we couldn't get anywhere close to the official maximum 4K random read figure, the FX900 Pro is the fastest consumer drive we've tested to date for random reads at QDs 1, 2 and 4. In contrast at QD32, the drive sits in the bottom section of the results graph.
