I dunno bout the "porsche designed" sounds a bit gimmiky really. I have the Lacie Firewire 80gb ecternal hdd to back up our 2 laptops and it works with no problems.
Got it as a warrentied customer return from dabs was about 40% off original price.
I use it about once a month. with a mac program called carbon copy cloner which basically just photocopies the hard drive across to the external.
You can drag files back and forth of you dont want to do the whole thing.
