Hitachi Releases Travelstar 5K320 Hard Drives

International Desk, Feb 28, 2008
Hard disk drive manufacturer Hitachi Global Storage Technologies announced volume shipment of its new 2.5-inch 5,400 RPM notebook hard drives with a maximum available capacity of 320 GB.
The Travelstar 5K320 is designed to support the multitasking needs of consumers and commercial users balancing mobile computing and movies, music, photos and games on-the-go. The new drives feature optional Bulk Data Encryption (BDE) for users requiring increased data security and enhanced availability models designed for use in 24x7 environments.
Travelstar 5K320's Serial ATA (SATA) interface provides 3Gb/s data transfer rate, allowing the drive to be used in a wide variety of applications including mainstream computing, portable external storage devices, small form factor video devices, game consoles and other advanced mobile devices.
New enhancements include altitude-sensing Thermal Fly-height Control (TFC), an improved actuator latch and fourth generation perpendicular magnetic recording (PMR) head technology. These features combine to safeguard user data that might otherwise be compromised as a result of accidental falls, bumps and rough handling. The drives also include TrueTrack technology, which improves tracking accuracy in high shock or vibration environments. These features combine to deliver 400Gs of operating shock protection.
The new drives consume 1.8W of power when reading and writing and their .55W low power idle means longer battery life for more "unplugged" notebook time and a longer drive life expectancy.
"The Travelstar 5K320 addresses a growing demand for high capacity hard drives, which are at the heart of today's notebook PCs, external storage devices, gaming consoles and other mobile computing applications," said Larry Swezey, director, consumer and commercial HDD, Hitachi Global Storage Technologies. "And when coupled with our optional Bulk Data Encryption technology, the Travelstar 5K320 offers even greater value to notebook users by helping to guard against data theft."
The Travelstar 5K320 is available in single or dual-platter configurations with capacities between 80 GB and 320 GB. The 320-GB version can hold up to 320 hours of digital video, 160 PC computer games or 80,000 four-minute songs. Hitachi will also offer an enhanced-availability (EA) version of the drive that is designed for applications requiring 24x7 operation in lower transaction environments, such as blade servers, network routers, point-of-sale terminals and video surveillance systems.
