I have been ripping my DVD collection which is taking up the bulk of the drive. I also mess around with photography as a hobby with my DSLR and Aperture, so that takes up a bit of room as well. I have decided it's time to get an external hdd. I will most likely go with a bare drive and get a separate enclosure. My main question is whether I need FireWire for the connection. As I said, this will be my storage location for my movies that I stream from the iMac across the network and possibly photos in the future with Aperture. And if FireWire is needed, is 400 sufficient, or should I just spring for the 800. For the drive itself, should I go for 7200 rpm or would 5900 be ok? The enclosure I'm leaning towards is the OWC mercury elite-al quad interface as I've seen it recommended around here quite a bit. I'm just wondering if this is overkill and I could save money by going with either FW400 or simply USB. As a side note, I do intend to get a second drive to use as a backup (universal USB connection on that one) Thanks for any insights.
