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 recorded nearly identical performance as the OCZ Vertex 3 240GB. Both drives share the same controller and same Intel 25nm NAND flash, so this wasn't a big surprise. The two drives when tested used different firmware.
The newer firmware on the S511 allowed the ADATA drive to outperform the OCZ Vertex 3 240GB. This is an area where SandForce is making strides to increase performance.
