I could use some help I am trying to set up a good external HDD system for my MBP CD. I don't want to spend an enormous amount of money (under 300 would be best) I am going to be using this/these hard drive(s) for final cut scratch disks, and possibly back up when Time Machine comes out with Leopard. I have these interface options FW400, USB 2.0, or some other interface (FW800, eSATA???) via an ExpressCard Can someone help me find a good link to what I need. I dont quite understand how the whole purchasing-external case-separately-thing works. Thanks for your help.
