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 spacingfive disks are
stacked in only 17 mmto 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.
IBMs 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 sectors ID
field. The Partial Response Maximum
Likelihood (PRML) digital channel enables
higher areal densities, significantly
contributing to the drives 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 todays
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.
