Leading-edge technology
Hitachi continues its tradition of mobile storage leadership with the Hitachi Travelstar 40GN hard drives. The innovative hard drive design combines AFC Media, Fluid Dynamic Bearing (FDB) motor technology, an ATA-100 interface, Hitachi giant magnetoresistive (GMR) head technology, Partial Response Maximum Likelihood (PRML) digital channel, a head load/unload feature, and Enhanced Adaptive Battery Life Extender (ABLE) 3.0. This design provides the exceptional quietness, storage capacity, performance, power management, quality, and reliability required by today's notebook systems.

The Travelstar family of hard disk drives incorporates the latest Hitachi storage technology-antiferromagnetically coupled (AFC) media, informally known as "pixie dust." This technology sandwiches a three-atom-thick layer of ruthenium, a precious metal, between two magnetic layers on a disk, allowing for a higher "pixie dust" areal density, breaking through limitations of the super paramagnetic effect.

As a result, the new Hitachi Travelstar drives are suitable for demanding, high-capacity Internet, digital audio, video streaming, and real-time multimedia applications-whether users are in the office or on the road. In nontraditional applications, Travelstar drives can now incorporate into such products as Point-of-Sale Systems, Set- Top Boxes, Telemetry (automobile) applications, and communications and entertainment systems.

Performance and reliability
The Hitachi Travelstar 40GNX hard drive uses proven Hitachi technology such as TrueTrack Servo,Hitachi Drive Fitness Test (DFT) and Self-Monitoring Analysis and Reporting Technology (S.M.A.R.T.),as well as a thermistor, an adaptive control device that helps maintain high performance and fast seek times at high environmental temperatures. .

Enhanced Availability models
Hitachi also offers enhanced availability features on selected new Travelstar models. These industry-first models increase the hard disk drive's available "power-on" hours for emerging applications with continuous operation. At a read/write or data access rate of up to 50 percent - a typical usage cycle for 24x7 blade server environments - the drives are designed to allow users to leave these drives powered on around- the-clock.

Advanced mobile systems
With these new drives, Hitachi has once again redefined state-of-the-art storage for mobile computing. The reduced acoustics, high speeds, and capacities of Hitachi Travelstar drives support superior digital content creation capabilities, higher quality digital audio and video, and significantly faster processing for data-intensive multimedia and Internet applications.

By using one of the new Travelstar drives in a laptop system, you can unchain your multimedia studio from the desktop, enabling high-end multimedia creativity as mobile as your imagination.
