CrystalDiskMark is a disk benchmark software that allows us to benchmark 4K and 4K queue depths with accuracy.

Key Features:-

* 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.

Both of the new revisions to the Marvell SATA 6G controller (found in the Corsair Performance 3 and Crucial m4 in this chart) have slower 4K read performance than the original RealSSD C300. We know that the version used in the Performance 3 took a little away from this area and used it for better garbage collection / dirty drive performance. The Crucial m4 does a little better job at 4K reads when compared to the Performance 3, and a much better job when NCQing comes into play. Still, in all 4K and 4K NCQing tests, the m4 is slower than the RealSSD C300.

When we previewed the ADATA S501 last June we noticed that NCQing wasn't working while writing data to the drive. The same was also observed with the Corsair Performance 3, but as you can see Crucial managed to not only to get NCQing working, but also increase their QD:1 (single) 4K write speed over what the Vertex 3 offers. At depth the Vertex 3 regained the 4K write lead.
