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 gave us some surprises as well. Here we are looking at 4k and native command queuing performance and the SanDisk Ultra disappointed us again. In the read tests we see the Ultra delivering half of the 4K read speed as the Vertex 2 and the NCQ performance was off as well.




Things were different in the write tests. The 4K single command result was actually faster than the Vertex 2 120GB drive, but the depth tests were still a little slower.
