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.




CDM gives us sequential, 512b, 4K and NCQ performance, all with incompressible data. The Crucial m4 mSATA delivers around 24MB/s of read 4K performance. The drive scales really well when we ramp up the requests. The QD4 4K performance reaches nearly 85MB/s and that goes to 192MB/s at QD32.




In HD Tune Pro we see compressible sequential performance, but in CDM we see incompressible numbers. Here we see that the Crucial m4 is faster than the SandForce drives when working with incompressible data and writing sequential data.


The 4K write performance of the m4 is a little slower than the SandForce drives (MemoRight MS 701 and MDSSD SMART).
