Need a bigger drive in your laptop? Seagate's 160GB notebook drive is just the thing for those of you ready to scrap your desktop PC. Being touted as the first 2.5-inch notebook PC disc drive to use perpendicular recording technology, the aptly-named Momentus 5400.3 drive is a 5,400-rpm drive that operates with 4,200-rpm power efficiency and the perpendicular recording makes the drive density larger by standing data bits on end on the disc, rather than flat to the surface. And all this promises not to drain your battery life. Weighing less than a pound, it's powered through a USB port and transfers data at 480Mbps.
