I need a larger drive for backing up my iMac and MBP. I was looking at a Guardian Maximus (which I might still buy), but then I thought why don't I replace my 500GB time capsules drive with a 2TB drive. I checked newegg and there was a couple of 2TB drives that I saw. $120 - Hitachi Deskstar HD32000 7200RPM $130 - WD Caviar Green WD20EARS Since its going in a Time Capsule, I'm not sure speed is as important and heat and vibration. I am also looking for an external enclosure for the 500GB drive with FW800, but the cheapest I found was $60. The other option is getting a $23 USB2.0 enclosure. Anyone have other recommendations or experience replacing the Time Capsule drive? Thanks for the help.
