Full speed, sheilded cable, designed to connect to an external HDD cage.
Thinking about picking up a 500GB WD SATA drive, an expresscard esata adaptor, and a ESATA enclosure. Expensive at like 60 cents per gig, but still. Be nice to be able to bring my files with me instead of almost none of them. Between the game installs and the images, Ive got over half of my drive storing games.
Im waiting for somebody to throw a pair of 2.5" bays inside a battery/optical bay sized enclosure. Get some decent storage inside a laptop for a change.
