Samsung intros perpendicular notebook hard drives

A little behind its competitors—Seagate, Hitachi, and Fujitsu—Samsung has at last introduced some notebook hard drives with perpendicular recording technology. The hard drives are part of a new M80 line, and they pack 80GB, 120GB, or 160GB of storage capacity into platters that spin at 5,400 RPM. The drives all feature 8MB of cache and come in 2.5" enclosures with either Serial ATA or IDE support. Samsung has also engineered these drives for quiet: the M80 series includes both fluid dynamic bearings and a so-called Hybrid Latch System that cuts down on seek noise.

Last but not least, Samsung's new drives integrate a new free-fall sensor. Thanks to this sensor, the company claims an impressive 700G of operating shock tolerance for the drives. That figure is twice as much as the rating for Seagate's Momentus 5400.2 (PDF) hard drives and over double that of Hitachi's Travelstar 5K160 drives. Samsung only offers a three-year warranty for its drives, though, while Seagate offers five years of coverage.
