CrystalDiskMark is a useful benchmark to measure theoretical performance levels of hard drives and SSD’s. We are using versions 6 & 8 for testing.
In the CrystalDiskMark QD32 single-threaded benchmark test runs, the scores of 312MB/s and 296MB/s for reads and writes respectively put the Acer SA100 into mid-position in the results table. We could confirm the official Sequential 560MB/s read performance with a tested score of 562MBs and also the official write figure of 508MB/s with the best test result of 514MB/s.
CrystalDIskMark 8
Once again we could confirm those official Sequential figures with CrystalDiskMark 8. Looking at the two benchmark result screens it appears that the Maxio MAS0902A-B2C controller in the SA100 doesn’t have a preference in the type of data it is being asked to work with.
CrystalDIskMark 8 – Peak Performance Profile
CrystalDiskMark 8 includes a couple of profiles that can be used for testing – Peak Performance and Real World. The result screens for these two profiles not only display MB/s results but also IOPS and latency.
CrystalDIskMark 8 – Real World Profile
Acer quotes 4K random performance for the 1.92TB drive as up to 76,000 IOPS for reads and up to 77,000 IOPS for writes. Testing the drive with the Peak Performance profile, the best read figure produced by the drive was 74,906 IOPS with writes at 68,087 IOPS, both short of the official figures.
