CrystalDiskMark is a disk benchmark software that allows us to benchmark 4K, and 4K queue depths with accuracy.
* Sequential reads/writes
* Random 4KB/512KB reads/writes
* Text copy
* Change dialog design
* internationalization (i18n)
Note: Crystal Disk Mark 3.0 Technical Preview was used for these tests since it offers the ability to measure native command queuing at four and 32.
As the chart shows, the RAIDR is average in nearly all of the tests. The sequential read performance is higher than most of the other drives on the chart, but some of the 2.5" drives are still faster.
The write tests in CDM show the RAIDR Express in a good light. The two drives in RAID configuration increase the incompressible data performance over a single controller SF-2281 drive.
