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.
4K reads nearly reach 30MB/s and the 4K performance scales well from there as the queue depth increases.
4K writes are nearly 135MB/s and scale to QD4, but 4K QD32 falls back a bit. The QD4 result is so high that we can look past the decrease at high queue depths.
