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 our first look at incompressible data performance. When reading data, there isn't a lot of difference between data types - we'll see a larger divide in the next chart when writing data to the drive. Reading data we see good scaling with added queue depth, from 39 MB/s at QD1 to 88 MB/s at QD4.




Incompressible data doesn't do a lot of harm with 4K writes, as you can see in this chart. The sequential performance with incompressible data moves down to 331 MB/s.


So much for the forum complainers - the Prevail 240GB outperforms Crucial's M500 240GB when writing sequential incompressible data.
