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.
In CDM we see the IOPS performance in MB/s in the three 4K tests. As expected after seeing the performance on the previous page, the 4K read performance is down compared to Intel's 520 Series and OCZ's Vertex 3 Max IOPS, both with LSI SandForce controllers.
The V300, 120GB SF penalty, AKA the brick wall, kicks in at a lower speed than the other LSI SandForce 120GB drives we've tested. The QD1 4K is higher than the 520 Series and Max IOPS, though.
