Seagate has begun
shipping the industry's first 2.5-inch notebook PC disc drive built on
perpendicular recording technology to the worldwide distribution channel.
Delivering up to 160GB of capacity, the most available in a 2.5-inch disc
drive, the Momentus family continues to close the capacity and performance gap
between desktop and notebook PC hard drives to help meet growing demand for
fast, high-capacity notebook computers.
Momentus 5400.3, a 5,400-rpm drive that operates with 4,200-rpm power
efficiency to extend battery life, is Seagate's first to bring the higher
capacities and performance of perpendicular recording to mainstream notebook
PCs. With Momentus 5400.3, Seagate once again leads the industry in areal
density, delivering 132 Gbits per square inch to provide the highest levels of
drive capacity, reliability and performance. Seagate will also extend the
advantages of perpendicular recording to its 7,200-rpm Momentus disc drives
and to all of its 1- and 3.5-inch products.
Perpendicular recording stands data bits on end on the disc, rather than
flat to the surface as with existing longitudinal recording, to deliver new
levels of hard drive data density and capacity. The new data orientation also
increases drive performance without increasing spin speed by allowing more
bits to pass under the drive head in the same amount of time. The
perpendicular recording performance boost comes without increases in power
consumption or heat generation -- crucial as remote users look to work longer
between battery charges and system builders seek to pack more performance in
smaller notebooks. Perpendicular recording also improves drive reliability by
enhancing data resistance to thermal decay.
The Momentus 5400.3 hard drive now shipping to the channel features the
Ultra ATA 100 Mbyte/second interface. Seagate will begin shipping Momentus
5400.3 with the 1.5 Gbit/second Serial ATA interface later this year.
The Momentus family is built tough to withstand up to an industry-leading
350 Gs of operating shock and 900 Gs of non-operating shock to protect drive
data, making the drives ideal for printers, copiers, non-mission critical
blade servers, external storage arrays and other non-PC environments where
systems are jarred or subject to a rugged operating environment. The hard
drives are also lean on power, allowing notebook users to work longer between
battery charges, and are virtually inaudible thanks to Seagate's innovative
SoftSonic fluid-dynamic bearing motors and QuietStep ramp load technology.
Momentus - Delivering a Range of Solutions for System Builders
Perpendicular recording is a key addition to the 2.5-inch Momentus family,
allowing the drives to deliver higher capacity and performance without
increasing spin speed, power consumption or heat dissipation. With Momentus,
Seagate is redefining mobile computing by delivering rugged, power-thrifty
hard drives that combine whisper-quiet operation with new levels of
performance and capacity.
The Momentus family gives system builders a range of spin speeds
(4,200-, 5,400- and 7,200-rpm), capacities (40GB to 160GB), and interfaces
(Serial ATA and Ultra ATA), allowing them to offer a variety of differentiated
systems ranging from low-cost and mainstream notebook PCs to high-performance
mobile workstations, small form factor PCs and blade servers. The drives are
covered by Seagate's industry-leading five-year warranty for customers that
buy through authorized distribution.
