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 been observing a lot of variation between different companies SF-2281 controlled drives and the native command queuing performance. The straight one command 4K runs have all been around the same, around 38MB/s, but the 4 and 32 command tests have been vastly different.
The Mushkin Chronos Deluxe does a really good job in the 4 command area scoring 81MB/s, one of the highest results we've recorded. The 32 command test showed a score of 207MB/s which is a little lower than we expected, especially for a drive that has such a large IOPS rating.
The single command 4K write test produced an impressive 132MB/s, another very high score, but again the higher queue depth tests weren't as high as we like to see. The high queue depths are rarely seen in desktop level applications or used, so we aren't too worried about the results.
