CrystalDiskMark is a useful benchmark to measure theoretical performance levels of hard drives and SSDs. We are using v8.0.
Using the default CrystalBenchMark 8 4K QD1 T-1 benchmark the read result of 69.46MB/s sees the Exceria Pro sitting in the lower mid part of our results chart. The write result of 246.82MB/s is much better than the other drives with read results in the 60MB/s range.
Looking at the default benchmark result screens we could confirm the official Sequential maximum read figure of 7,300MB/s with a test result of 7,382MB/s (7,417MB/s using compressed data). Tested Sequential write performance came up a little short of the official 6,400MB/s at 5,796MB/s (5,845MB/s using compressed data).
That tested read score of 7,382MB/s puts the drive into the top 5 in our results chart although just like the Teamgroup T-Force drive just above it, the write test results aren't anywhere near the top two drives in the table.
Switching over to the CrystalDiskMark 8 Peak Performance profile we could once again confirm the official Sequential read figure with a test result of 7,383B/s. However, write performance at 5,793MB/s again came up short of the official maximum figure.
The 4K test results had both reads and writes far below the official figures. The 2TB Exceria Pro is rated up to 800K IOPS for reads and 1.3M IOPS for writes. The best read result we saw in the default CrystalDiskMark Peak Performance test was 646,906 IOPS for reads and 530,872 IOPS for writes.
Using the Real World profile sees the drive sitting just inside the top 10 drives with a Sequential read result of 4,031MB/s while write performance is much better at 5,570MB/s.
