The gap in capacity between a desktop and a laptop is definitely diminishing – especially now that Seagate has released its 160GB notebook drive – the first 2.5-inch notebook PC disc drive to use perpendicular recording technology.
The Momentus 5400.3 is a 5,400-rpm drive that operates with 4,200-rpm power efficiency to extend battery life. Perpendicular recording increases drive density by standing data bits on end on the disc, rather than flat to the surface. Seagate claims this new data orientation also increases drive performance by allowing more bits to pass under the drive head in the same amount of time. And best of all for notebook users – this extra performance doesn’t add to the drain on battery power.
The portable drive is designed to be portable, weighing less than a pound, is powered through the computers’ USB port – so no power cord and data can be transferred at a very decent 480Mbps.
