On the mobile front, Seagate is unveiling the Momentus 5400.3. Spinning at 5,400RPM, the drive supports Native Command Queuing, comes in capacities up to 160GB, and is also covered by Seagate's five-year hard drive warranty. Interestingly, Seagate claims that the new Momentus is the industry's first perpendicular recording technology drive. Perpendicular recording improves areal density by arranging bits perpendicular to the recording surface rather than parallel to it. For more on the technology, be sure to check out Hitachi Global Storage Technologies' disco-riffic presentation on the subject.
