CrystalDiskMark is a disk benchmark software that allows us to benchmark 4K and 4K queue depths with accuracy.
* 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.
In CDM we are looking at 4K and NCQ performance. This is another area that can be tuned by changing the stripe size of your array and a few of the numerous settings on the controller. With our default settings we see the Areca ARC-1882i outperform the 9265-8i in every low queue depth (1 and 4), but with a queue depth of 32, the LSI controller is a little faster.
Things ran a bit differently in the write test, both controllers went back and forth depending on the type of RAID used.
