Momentus 5400.3, a 5,400-rpm drive, will be Seagate's first to bring the higher capacities and performance of perpendicular recording to mainstream notebook PCs and non-PC applications including external storage, commercial printers and copiers, and non-mission critical blade servers. Next year Seagate will extend the advantages of perpendicular recording to Momentus 7200.1, a 7,200-rpm drive designed for mobile workstations and other high-performance notebook computing applications.
