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.
The single queue 4K read test gave us a solid 30MB/s, around 5 to 10 shy of the fastest SF-2281 result we've seen. Once the commands stack up though the Performance Pro takes off, the 4 command NCQ score went up to 108MB/s, nearly double that of the Vertex 3 240GB. The 32 command 4K read test was also impressive, here we almost hit 300MB/s.
CDM uses incompressible data and it should be noted that the Performance Pro doesn't worry about what type of data it's reading or writing. The drive delivered really good write numbers in these tests, but the results were much closer to the higher end SandForce drives.
