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.


We've only had two 2.5" drives break the 40MB/s QD1 4K read mark, the Samsung 840 Pro and the SuperSSpeed S301 SLC. When moving to QD4 the Samsung steps away from the pack and delivers a blazing 137MB/s.


When it comes to 4K write performance, the OCZ Vector is a bit faster in all three of the 4K write tests. CDM uses incompressible data and surprisingly enough, the SuperSSpeed S301 SLC is quite a bit faster in the sequential write test.
