CrystalDiskMark is a disk benchmark software.


Key Features:-


* Sequential reads/writes
* Random 4KB/512KB reads/writes
* Text copy
* Change dialog design
* internationalization (i18n)


Note: Crystal Disk Mark 3.0 is not available to the public yet, but the Technical Preview does allow us to test 4K performance at queue depths of 4 and 32 in addition to 1. The current release Crystal Disk Mark only shows us QD 1.




We use CDM to look at 4K and 4K at queue depth (NCQ) performance. The Vertex 3 has just a slight advantage over the Vertex 2 in 4K single command performance but once we start stacking up commands things get interesting. At 4 commands the Vertex 3 is actually slower than the Vertex 2 but at 32 commands the the Vertex 3 takes off and is able to deliver nearly 200MB/s.




The 4K write performance is nearly the same as the Vertex 2 240GB, but in this case the 4 and 32 queue depth really take off and outshine everything else we've tested before.
