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.




In CDM we're looking at the 4K results (top three bars in each group). For the most part the 512GB Vertex 4 stayed the same except for a slight performance increase at 32 queue depth. The 256GB model lost a little performance at QD4, but gained around 45MB/s at QD32.




In the 4K write test the performance stayed about the same.
