This is attracting setup well, will give it one try... bonnie++ is your friend. http://www.coker.com.au/bonnie++/ And for RAID any higher than 1, you need a storage array.

Usually when BIOS messages appear for RAID controller, it tells you what keys to use to get into BIOS configuration of that RAID card. It could be ctrl-m for example.
