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.




Using multiple threads to get a sequential read number we see the Vertex 4 256GB does get a nice boost over the last firmware, around 85MB/s to be specific. When copying data over for my fill test it was clear that the Vertex 4 was much faster this time around in preparing that test.




The sequential write speeds with threads took on a nice performance increase as well.
