When I go on the road my laptop has a 40 Gig drive but that is just not enough and I carry a 60 Gig Firewire external just to have all of my data with me. Finally someone has developed a 100 gig 2.5 inch hard-drive. Time will tell how these will perform. Japanese techies are going to get a shot at them first but they will not be cheap. [Engadget]
