Kioxia BG5 1TB SSD Review

CrystalDiskMark is a useful benchmark to measure the theoretical performance levels of hard drives and SSDs. We are using v8.0.

The 1TB BG5 performs reasonably well in CrystalDiskMark 8's 4K QD1 test with a read score of 75.92MB/s which is good enough to see the drive creep into the top ten. Its write result of 202.36MB/s is a bit on the low side though.

Using the default settings of CrystalDiskMark 8 we could confirm the official 3,500MB/s Sequential read rating but fell a little short of the official write figure of 2,900MB/s. However, using the 0 fill option we could also confirm this figure.

Using the Peak Performance profile of CrystalDiskMark 8 we could confirm both official 4K random figures; up to 500,000 IOPS random reads and 450,000 IOPS random writes with test results of 530,527 IOPS for reads and 486,172 IOPS for writes.

Using the Real World profile we saw Sequential read/write scores of 3,006MB/s and 2,792MB/s respectively while the drive produced a random read score of 18,539 IOPS with writes at 50,466 IOPS.
