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.
CDM is our last synthetic benchmark and we use it to observe 4K and native command queuing performance.
4K performance with the new SandForce SF-2200 works a little different than what we measured on the SF-1200 drives. In a single call for data the OWC Mercury Extreme Pro is faster than the Vertex 2's SF-1200, but the 1200 is faster when NCQ is used. The SF-2200 is still very fast delivering almost 60MB/s at a depth of 4 and 115MB/s at a depth of 32. The depth tests are slower than the Crucial m4, though.
The write 4K single request result was very fast, over 120MB/s, but once NCQ came into play the OWC Mercury Extreme Pro topped out at 163MB/s in both 4 and 32 commands.
