god point, right now im using an old WD My Book it has a 6 pin firewire, so im assuming its firewire 400, based on what ive researched that is not faster by much if at all than usb 2.0? i guess as long as the backups dont take much longer than they currently do i would be happyUnless you're concerned about getting the backups done in a particular timeframe, then yes, it's fast enough. I use 2.0 to do my Time Machine backups on my MacBook Air hourly and have no issues.
if you're using time machine (i don't, personally), an incremental backup is not going to take much time at all.I know everyone is different, but I'm surprised how many people find USB 2.0 usable.
USB 2.0 is too slow for me. Sure it doesn't matter much if you don't mind the time, but I personally do all my backups over Gigabit Ethernet.
lots of uses for usb 2.0.Shouldn't be too surprising. $$ trumps many other things for most people it seems.
Get Firewire if $$ is not an issue, or if the price for firewire interface is comparable to USB. You never know what you might plan to use your HD for in the future.all i plan on using my external HD for is backups, using CCC is USB 2.0 Fast enough of will it be worth my while to spend the extra 30-40$ for a drive with Firewire 800?
