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 are looking at NCQ performance and how it scales at the 4k block size. The RunCore Pro V Plus delivers about half the performance as the older model Vertex 2.
NCQ performance is even worse when writing data. From the numbers delivered I'd say that NCQ isn't working at all, but the brick wall of pain is actually limited by the flash and not the SandForce controllers design.
