I am looking for a good External Hard Drive to use with my MBP running Time Machine. I have looked at the MyBook Studio Edition since it is quad interface. I know the Mac doesn't support eSATA but I think it will before long. I most likely will use the Firewire 400 or Firewire 800 port on my MBP and am looking for something that holds 750GB since my MBP has a 250GB HD. I have looked at the various Western Digital My Book's such as the Pro Edition with the 3 interfaces but also am wondering if something from Seagate, Maxtor, Lacie, or OWC would be better.
