IBM DCXA-210000 Reference Guide

Capacity leadership and exceptional performance
provide flexibility for mainstream mobile computing

IBM Travelstar 10GT Hard Disk Drive

Highlights

Industry-leading capacities of

10.0 GB and 8.1 GB, in a 12.5 mm
form factor, allow mobile users
to store and access large appli­cations and high volumes of
data—all from a single drive.

Fast data rates, high RPM (4200),
and a large 512 KB data buffer
enhance performance without
increasing power consumption.
Ultra DMA provides an interface
transfer rate of 33.3 MB/sec.

Drive Fitness Test* (DFT), an
innovative IBM technology,
helps reduce end-user disrup­tion and the expense of disk
drive replacement.

Industry-leading 12.5 mm
shock ratings of 600 G/2 ms
(nonoperating) and 125 G/2 ms
(operating) help increase rug­gedness and reliability.

Enhanced Adaptive Battery Life
Extender* 3.0 power manage­ment technology selects the
appropriate mode to help mini­mize power usage and increase
battery life.

Leading drive technology

The Travelstar* 10GT is ideally suited for
the large capacity demands of integrated
Internet/intranet, video, and multimedia
applications in a standard mobile
computing environment.

To provide this high level of performance,
the Travelstar 10GT employs proven IBM
technology. Giant magnetoresistive
(GMR) advanced head technology
increases areal density, reducing the
number of disks and heads required to
provide each capacity point. The GMR
head technology increases areal density
to more than 5.6 Gbits/sq. inch, and its
pico slider enables more disk surface to
be read. IBM disk drive technology
enables the Travelstar 10GT to provide the
exceptional capacity, performance, power
management, shock resistance, and
reliability required by today’s main­stream notebooks.

Quality leadership

As a member of the Travelstar family,
the Travelstar 10GT shares proven
common components with the Travelstar
14GS and the Travelstar 6GN—PCBA,
microcode, head, slider, and disks.
The use of common components,
combined with advanced design
and state-of-the-art manufacturing,
provides superior quality drives and
reduces overall cost of ownership.

Time-to-market advantage

The Travelstar 10GT enables notebook
manufacturers to quickly provide
industry-leading capacity, perfor­mance, power management, and
shock resistance to notebook users.

IBM support and service

The Travelstar 10GT is backed by an
array of IBM technical support and
services. This support package is
designed to help ensure that IBM
customers can easily integrate the
Travelstar 10GT into their design and
quickly develop and manufacture
high-quality, cost-effective systems.
