I don't know why this guy would need a RAID. It seems like overkill or misdirected nerdiness, depending on how he set it up. If he had 2 internal drives in a RAID he gains nothing. Backup maybe if he mirrored the drives. Video should be edited on a dedicated drive so he gains nothing. System/apps on the internal drive and multiple external drives in a RAID? Overkill.
Just get a second drive--external would be good because when you're not working on movies it makes a good backup drive that you can stick in a safe or something. Keep it simple unless you have good reason to do otherwise.
