OK, I know this is a bit of a stupid question but like all computer purchases I like to get the informed opinion of the MR community first. I'm looking at buying a large external HD for archiving my DVD collection. I have a habit of scratching dvds and lending dvds to people who forgot to return them. So what ports should I get that will be of use to me in the next 5-10yrs (or whatever the lifetime of the external HD is). FW400 looks doomed, will FW800 soon dissapear also? Will USB be superseded soon also? USB2 only drives are the cheapest, so I'd like to avoid paying extra for FW and then see it disappear in a few yrs. I know this all speculation I just want the best ports for as long as the HD lives. I currently have a MacBook but will soon get a MacBook Pro (i'm lucky, I know).
