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.

The P44 Pro performance in our 128KB Sequential tests seems to plateau out from QD's 2-8 for both reads and writes. The performance for both then rockets away, the reads climbing as the queue depth deepens to finish the test run at 7,371,94MB/s, 371MB/s faster than the official figure. The write performance rises in a similar manner but plateau's out again between QD's 16 and 32. Peak writes come at QD16 at 6,584MB/s, 84MB/s faster than the official maximum.

128KB Sequential Read v QD comparison

The drive's best performance in relation to the drives around it comes at QD2 (where it sits third in the results chart) and QD32 (second spot in the chart). At QDs 1 and 4 it still performs well, good enough to retain a top 10 spot at these two queue depths.

128KB Sequential Write v QD comparison

When it comes to our Sequential write tests, the drive's performance at lower queue depths is nothing to write home about but at QD32 the drive seems to come alive, its test result of 6,582.69MB/s not only confirms the official maximum of 6,5000MB/s, it is also the fastest Sequential write performance for a 1TB class consumer drive we've seen to date.
