CrystalDiskMark is a disk benchmark software that allows us to benchmark 4K and 4K queue depths with accuracy. Key Features:-* 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.

The single command 4K read performance is the second best on the chart. We observed good scaling when going from 1 to 4 commands and another nice increase when moving to 32 commands.

The 4K writes seem to be an issue with the SandForce controller and 16 ultra high-density flash chips. All of the 4K write tests are lower than what we get with 240GB and even 120GB SandForce based SSDs.
