your best bet is to just buy a 1TB SATA drive, and buy a SATA USB and/or Firewire drive enclosure, which will make the drive portable and easy to connect.
As for models, I prefer western digital and samsung.
as for drive enclosures, they're all made overseas, they're all generic and fragile looking, but since you live in Rohnert Park, goto Fry's Electronics and get this:

the enclosure's work very well and I have several different brands, there's no one better than the other. the one I listed I like because it seems to absorb heat better.
I had one with a cooling fan on it, I think it's in a bin somewhere, but I haven't found them anymore at fry's, doesn't mean it isn't there tho.
