So, I'm thinking about getting a new external hard drive specifically so I can boot up with FW800 and run Final Cut Pro (so it doesn't use my internal space...) My question - would it be a better decision to simply get a good External Enclosure and put a big internal drive inside that or just a regular external enclosure? It seems it's much cheaper to do it that way... I saw this enclosure: OWC OWC Mercury Elite Pro FireWire 800/400 + USB 2.0/1.1 Combo Case Kit: then maybe popping in a 500gb hard drive - seems a ton cheaper (and it's possible I could throw in an even larger drive..) what do you guys think of that? any experiences with doing something like this? thanks!
