I am using 4 brand new disks, so I do not plan on rebuilding for a time (I hope so!).
Even in case of disk failure, is rebuild possible via Intel BIOS Utility??

Daniel -
Keep in mind that dm-raid4-5 is still considered 'experimental.'
Raid5 would work fine in a home environment as long as you do not plan on rebuilding after a failure [at the moment]. Since the dm-raid4-5 patch is still considered experimental, you should weight your risks of data loss.
I have tested Heinz's dm-raid4-5 patch on several ICH systems and have had good success with it; even after pulling a drive out to simulate a failure. If a failure would occur, you would have the opportunity to back-up the data before the set completely failed.
Raid5 rebuild functionality isn't quite here yet. But it will be! Everyone is still working hard to update dmraid to rebuild failed sets.
