CrystalDiskMark is a disk benchmark software.


Key Features:-


* Sequential reads/writes
* Random 4KB/512KB reads/writes
* Text copy
* Change dialog design
* internationalization (i18n)


Note: Crystal Disk Mark 3.0 is not available to the public yet, but the Technical Preview does allow us to test 4K performance at queue depths of 4 and 32 in addition to 1. The current release Crystal Disk Mark only shows us QD 1.




In CDM we are looking at the 4K read speeds. Here we see that the LSI MegaRAID in the block size we choose for testing didn't fare as well as the Areca controller did. This is one of the areas where users can tune performance, so we aren't too worried about seeing the lower 4K results. CDM is used by many enthusiasts as a benchmark standard and it is impossible to ignore the massive, over 2000MB/s sequential read scores from the MegaRAID.




The 4K write speeds can also be tuned to your liking by adjusting the block sizes. We are preparing an article that will explain and demonstrate this in the coming weeks. Look for it soon.
