CrystalDiskMark is a useful benchmark to measure the theoretical performance levels of hard drives and SSD’s. We are using v8.0.
Using the default CrystalBenchMark 8 4K QD1 T-1 benchmark the read result of 60.19MB/s sees the Exceria Plus G3 sitting in last place on our results chart. However, its write score of 350.50MB/s is the fastest we've seen to date for a 2TB class Gen 4 drive in this particular test.
Looking at the default benchmark result screens we could confirm both the official Sequential maximums of up to 5,000MB/s and 3,900MB/s for reads and writes respectively with a read test result of 5,074.24MB/s with writes at 3,974.20MB/s.
The Exceria Plus G3's Sequential read test result of 5,074MB/s puts the drive in the bottom section of our results chart.
Peak Performance profile.
Kioxia quotes 4K random performance figures for the 2TB version of the Exceria Plus G3 of up to 680,000 IOPS for reads and up to 950,000 IOPs for writes. When tested with the Peak Performance profile test in CrystalDiskMark 8 we could confirm those figures and even better them a little. The best read score we saw was 687,838 IOPS while the best write result was 967,388 IOPS using the default test.
As with the default test, we could confirm the official Sequential read and write performance figures with test results of 5,036MB/s and 3,974MB/s for reads and writes respectively.
Real World profile.
In the Real World profiles test the drive's Sequential read result of 3,236MB/s sees it firmly in last place on our results chart. However, its write performance of 3,957MB/s is some 721MB/s faster than the read.
