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 use CrystalDiskMark to look at two areas of performance. The first is 4K read and writes and native command queuing scaling. The Crucial m4 512GB delivers almost identical performance when compared to the OCZ Vertex 3 240GB. These two drives reside at the top of the chart. I'm a bit surprised at how close they are to each other. The other two m4 products are right there with them, but the 128GB m4 actually outperforms them both when commands are stacked.




CDM uses incompressible data, data that has already been compressed. SandForce drives handle this type of data differently since the controller actually compresses data in real time before it gets to the flash. The result is already compressed data is written to the flash slower than data that can be compressed; a sort of new age, digital sleight of hand.


When you take the SandForce magic out of the equation you get the results above. Here we see that once again, the m4 is really close to the Vertex 3 in the 4K and NCQ tests.
