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.

Here we're looking at 4K performance through a different lens. The M5M delivers 34MB/s at 4K QD1 and that jumps to 123.9MB/s at QD4.

Here we get our first look at sequential writes with incompressible data for the sample drives in the 256GB class of mSATA products. The M5M 256GB delivers the highest sequential incompressible writes we've seen with mSATA.
