Thank you for the help.
- The problem / doubt is the conflict that can happen in BIOS when I have two different Raids operating one in each controller (ICH10R - on bord and Rocket).
- For the that I researched, in the motherbords Asus you have to disabled the Raid of on-bord (ICH10R).
- If in the Gigabyte, the two simultaneous raids to work, I will buy SASs HDs, else I will buy Velociraptors (SATAII). Therefore the concern.
