I have a LaCie d2 Hard Drive Extreme with Triple Interface 500GB and never had any problems with it. I backup to it every week. I like it.
Some people say LaCie hard drives aren't good but this is the second LaCie we have bought in this household and we never had bad experiences with either of them.
Go to your local computer store and buy a case and a hard drive and put them together. This will, literally, save you hundreds of dollars.
