IBM DPLA-24480, DPLA-25120 Reference Guide

Increased capacity and enhanced performance
create a storage solution for true desktop equivalency
in a mobile computer

IBM Travelstar 5GS 2.5-Inch

4.4 and 5.1 GB Full Height Disk Drives

Highlights

Desktop equivalency

The highest storage capacity of 5.1 GB
and superior drive technology for high
performance provides desktop equiva­lency in notebook computing to meet
the most demanding requirements of
data intensive applications.

Performance leader

Fast access rates to large amounts of
data, demanded by integrated image,
video, Internet and multi-media applica­tions are provided by Travelstar 5GS’
media transfer rates.

Performance enhancements include
increased data buffer size (now 512 KB)
and the first mobile drive implementation
of Ultra DMA/33, improving the Interface
Transfer Rate to 33.3 MB/sec.

Improved power management

Enhanced Adaptive Battery Life
Extender
technology introduces a third idle mode,
in addition to Performance Idle mode
and Low Idle mode, and selects the idle
mode based on the individual user’s
access patterns.

2.0 power management

Leading drive technology

Travelstar 5GS meets the demands of
notebook and subnotebook users by
employing technology innovated and
developed by IBM. These include IBM’s
advanced head technology, Magneto­resistive Extended (MRX), Load/Unload,

TM

NO-ID
Response Maximum Likelihood (PRML)
digital channel and Enhanced Adaptive
Battery Life Extender 2.0 technology.

MRX advanced head technology offers
increased areal density, reducing the
number of disks and heads required.
Load/Unload technology enables the
use of smooth disks, allowing lower
Fly Height, resulting in improved areal
density and performance. No-ID
formatting increases storage capacity
by eliminating the overhead caused by
the duplicate storage of each data
sector’s ID fields and instead, uses that
disk space for a customer’s data. The
PRML digital channel allows higher
areal densities, significantly contributing
to the drive’s overall performance.

Combining IBM’s advanced technologies
allows Travelstar 5GS to achieve new
high capacity, high performance, and low
power dissipation required by today’s
high-end notebook operating systems
and data-intensive applications.

Interface

The Travelstar 5GS has an ATA-3 inter­face and supports a transfer rate of

33.3 MB/sec in Ultra DMA Mode-2 and

16.6 MB/sec. in PIO Mode-4, provid­ing optimum data performance and
industry compliance.

IBM quality and service

IBM drives are backed by a wide range
of technical support and services,
including customer support, qualifica­tion support, and integration assistance.
This comprehensive support package
ensures that IBM customers can continue
to develop and manufacture high-quality,
cost effective systems.

Data protection

S.M.A.R.T. (Self-Monitoring Analysis and
Reporting Technology) protocol support
protects data availability and helps alert
a system of impending drive failure.
