I'm looking for a 1 TB backup HD from my iMac. I like this because its small in size but has the storage space I want. Like the idea of the USB drive so I can just move it when I need to, to another machine with ease. But is this like a typical external HD for storage, where you can just drag and drop entire folders into it, w/o having to use any kind of firmware and you must run it in backup mode? I basically want a small HD like the Passport that I can just drag entire folders into w/o the need for any dedicated software or controls. How is the life expectancy in this little guy, is it like the Time Capsules that roll over a die far too often or do they last a good while? I have an old Maxtor External 320 GB HD that's going on 8 years old. If this isn't what I'm looking for anyone have any other suggestions?
