Bus architecture. Higher theoretical maximums on Serial ATA.
but not much higer in the current generation. Expect more in
the months to come.

SATA if you have SATA hardware and cabling. Otherwise, ATA/100,
a/k/a UDMA/100.

Serial ATA is newer, so adapter support isn't as broad as for
plain vanilla ATA.

In my order of preference: Seagate, Maxtor. Hitachi is missing from
this list because I've never owned one. Sometimes, Maxtor drives are
cheaper than Seagate, but I've had less problems with Seagate drives
than with Maxtor drives. That said, I've got a big fat Maxtor ATA/100
120GB drive in my primary box now, so we'll see how it holds up.
