I'm in the market for a good external drive (platter 2 TB) to use for Time Machine on my new iMac. I have 2 LaCie Porche drives that are several years old (one is a 165 GB Firewire 400 and that was huge when I bought it) and still running, however I read recently that the drives inside the new ones are Seagate which don't get much love and I am not sure if that's always been the case. Did LaCie once make their own drive? Can anybody recommend a good external drive for me? USB 3 of course and Bus powered would be great. Thanks as always. This is a great community that's always helped me.
