Phison PS5031-E31T 2TB Technical Preview (E31T Controller)

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 this test we couldn't quite confirm the official maximum Sequential performance figures for the PS5031-E31T of 10,300MB/s for reads with a test result of 10,173.7MB/s. However, we could confirm and even better a little the official 8,600MB/s rating with a result of 8,732.14MB/s (QD16).

128KB Sequential Read compared.

At QDs 1, 2 and 4 the drive sits on the bottom of the results charts a fair way off from the other Gen 5 drives. However, at QD32 the drive climbs up the table to lead the way for the 10GB/s drives.

128KB Sequential Write compared.

When it comes to the Sequential write test results the PS5031-E31T sits in the last spot on the results chart through all the tested queue depths.
