Hitachi DYLA-28100, DYLA-26480 Reference Guide

Increased capacity and exceptional performance provide

desktop equivalency for mobile computing solutions

IBM Travelstar 8GS

Highlights

Desktop equivalency

The highest available storage capacity

of 8.1 and 6.4 GB and superior perfor-

mance provide desktop equivalency in a

premium notebook computer.

Advanced design

An advanced electro-mechanical design

reduces disk spacingfive disks are

stacked in only 17 mmto provide an

industry-leading capacity of 8.1 GB.

Performance leadership

An industry-leading media transfer rate

(max. 107.6 Mbits/sec), a 512 KB data

buffer, 4900 RPM, and an Ultra DMA

interface transfer rate of 33.3 MB/sec help

meet demanding application requirements.

Superior power management

Enhanced Adaptive Battery Life

Extender 2.0 power management

technology includes Performance Idle,

Active Idle, and Low Power Idle modes. It

selects the appropriate mode to minimize

power usage and increase battery life.

Integrated Lead Suspension

An innovative new technology, Integrated

Lead Suspension (ILS), reduces the

number of moving parts and helps improve

dri ve re liabilit y.

Rugged design

Industry-leading 17 m m sh ock ratings of 400

G/2 ms (non-operating) and 12 5 G/2 ms

(operating) help increase reliability.

Leading drive technology

With its ability to quickly access large

amounts of data with its performance-

optimized design and superior capacity

of 8.1 and 6.4 GB, the Travelstar 8GS

provides outstanding performance on

the go for premium notebook computing.

The Travelstar 8GS is ideally suited for the

increased demands of integrated image,

video, Internet/intranet, and multimedia

applications in a mobile computing

environment. The Travelstar 8G S prov ides

enough capacity for users to load CD

applications onto the drive and run them

on the go.

To provide this high level of performance,

the Travelstar 8GS employs proven IBM

technology. Magnetoresistive Extended

(MRX) advanced head technology

increases areal density, thereby reducing

the number of disks and heads required

to provide each capacity point. The MRX

head technology increases areal density

to over 3 Gbits/square inch, and its pico

slider enables more disk surface to be read.

IBMs proven head Load/Unload technol-

ogy enables the use of smooth disks,

allowing lower fly height that results in

higher areal density. No-ID sector

formatting also increases storage capacity

by eliminating the overhead caused by the

duplicate storage of each data sectors ID

field. The Partial Response Maximum

Likelihood (PRML) digital channel enables

higher areal densities, significantly

contributing to the drives overall capacity

and performance. In addition, S.M.A.R.T.

(Self-Monitoring Analysis and Repor ting

Technology) protocol support improves

data availability by alerting the system of

impending drive failure.

All of these innovative IBM technologies

enable the Travelstar 8GS to provide the

exceptional capacity, performance,

power management, shock resistance,

and reliability required by todays

premium notebooks.

IBM quality and service

The Travelstar 8GS is backed by a three-

year warranty and a wide range of

technical support and services, which

may include qualification support and

integration assistance. This comprehen-

sive support package helps ensure that

IBM customers can continue to develop

and manufacture high-quality, cost-

effective systems.
