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 look at 4K and NCQ performance. This is also an area where the new Plextor M3 256GB starts to stand out from the pack of well designed SSDs. Looking at the Plextor drive compared to the Vertex 3 240GB, both read a single command 4K chunk at around 35MB/s. When you stack four commands the Plextor doubles the Vertex 3's speed. The gap closes up a bit at 32 commands, but the Plextor still has a 70MB/s lead.




When it comes to writing 4K data once again with a single command both the M3 and Vertex 3 are very close. The Vertex 3 takes the 4 command test, but the Plextor is back on top by 35MB/s at 32 commands.
