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 look at the 4K and 4K at queue depth. With the LSI 9260-8i the NCQ tests show very high scores; nearly 280MB/s. Some of this is due to the controller's cache. The ASUS configuration without cache was quite a bit slower.




The write tests show near equal performance for both configurations. Once again, though, we are looking at sequential transactions.
