We used CrystalDiskMark 8‘s custom settings to test the Sequential read and write performance of the drive through a range of queue depths. The setup for the tests is listed below.
128KB Sequential Read / Write.
Transfer Request Size: 128KB, Thread(s): 1, Outstanding I/O: 1-32.
In the 128KB Sequential read and write tests, the drives read performance climbs smoothly as the queue depth deepens, reaching 7,468.45MB/s at the end of the test run at QD32, a figure that just about confirms the official maximum speed of 7,400MB/s.
When it comes to write performance the drive rises rapidly in performance from QD1- QD2 then begins to plateau out with a peak of 6,707MB/s at QD16 before dropping back to end the test run at 6,694.65 MB/s.
Sequential Read Performance v QD compared.
The 2TB HP FX900 Pro is the fastest consumer drive we've seen to date for Sequential reads at QD1 (3,526MB/s). At QD's 2 & 4 it drops to third and fourth place respectively before topping the table again at QD32 with a test result of 7,468.46MB/s.
Sequential Write Performance v QD compared.
In relation to the drives around it, the FX900 Pro's best Sequential write performance comes at QD's 1 & 2 where it sits in sixth place. As the queue depth deepens further it begins to drop down the results chart.
