Kioxia BG5 1TB SSD 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 our own Sequential read/write tests we could confirm the official maximum figures of 3,500MB/s for reads and 2,900MB/s for writes with peak test results of 3,537MB/s (QD16) and 2,930MB/s (QD4) for read and writes respectively.

128KB Sequential Read Performance compared:

The BG5 performs best in relation to other drives around it at QD's 2 and 4 where it sits mid-table. At QD1 it's near the bottom of the table and at QD32, it sits in last place.

128KB Sequential Write Performance compared:

When it comes to Sequential write performance the drive sits firmly at the bottom of our results chart for all the tested queue depths,
