Kioxia Exceria Pro 2TB Review

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 7,425.97MB/s at the end of the test run at QD32, a figure that confirms the official maximum speed of 7,300MB/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 5,853.30MB/s at QD4 before dropping back slightly to end the test run at 5,845.10 MB/s, quite a bit short of the official 6,400MB/s.

128KB Sequential Read compared.

The 2TB Kioxia Exceria Pro is the slowest Gen 4 drive we've seen to date at QD1 but by QD2 it has closed the gap to its nearest competitor and continues to climb as the queue depth deepens until the end of the test run at QD32 by which time the drive is the fourth fastest consumer Gen 4 drive we've seen to date.

128KB Sequential Write compared.

When it comes to Sequential writes, the Exceria Pro sits in mid-table throughout the tested queue depths.
