IBM DCYA-214000 Reference Guide

Capacity leadership and exceptional performance provide
desktop equivalency for premium mobile computing

IBM Travelstar 14GS Hard Disk Drive

Highlights

The mobile industry’s highest
available storage capacity of

14.1 GB, combined with superior
performance, provides near­desktop equivalency for premium
notebook users.

An industry-leading media trans­fer rate (max. 125.5 Mbits/sec),
a 512 KB data buffer, 4900 RPM,
and an Ultra DMA interface
transfer rate of 33.3 MB/sec
help meet the most demanding
application requirements.

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

Industry-leading 17 mm
shock ratings of 400 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* 14GS 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 14GS 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 5.0 Gbits/sq. inch, and its pico slider
enables more disk surface to be read.
An advanced electromechanical design
reduces disk spacing, allowing five disks
to be stacked in 17 mm.

IBM disk drive technology enables the
Travelstar 14GS to provide the exceptional
capacity, performance, power manage­ment, shock resistance, and reliability
required by today’s premium notebooks.

Quality leadership

As a member of the Travelstar family,
the Travelstar 14GS shares proven co mmon
components with the Travelsta r 10GT
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 14GS enables premium
notebook manufacturers to quickly
provide industry-leading capacity,
performance, power management, and
shock resistance to notebook users.

IBM support and service

The Travelstar 14GS 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 14GS into their design and
quickly develop and manufacture
high-quality, cost-effective systems.
