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 4 and 32.
In CDM we are using incompressible data (data that is already compressed) to achieve the test results. Asynchronous flash has issues with this type of data, so there is a steep performance hit when compared to using data that isn't compressed.
When using high queue depths the RevoDrive 3 X2 really shines even when using incompressible data. Here we see a result of 511MB/s which was actually faster than the sequential write performance with this data type at low queue depths.
