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.
We've noticed that RAID has little effect on 4K reads and writes until you start piling commands with NCQing. Here we see the Patriot Wildfire following this same observed behavior. Once the Wildfire array starts getting 32 commands, the array takes off.
4K writes on the other hand get a decent boost when using a RAID 0 array. Using two Patriot Wildfire drives is even faster than the OCZ RevoDrive X2 that uses four 60GB drives.
