Leading-edge technology and innovative design for
high-performance, high-capacity mobile hard drives
IBM Travelstar 32GH, 30GT, and 20GN
2.5-inch hard disk drives
Highlights
The IBM Travelstar* 32GH offers
several industry firsts: a capacity of 32 GB, a media transfer rate
of up to 228.2 Mbits/sec, and the
first 4-disk 12.5 mm mobile hard
disk drive.
The new IBM Travelstar 30GT and
20GN hard drives provide areal
densities of 17.1 Gbits/sq. in. and
10 GB of capacity per disk.
The IBM Travelstar 20GN has the
industry’s highest shock rating of
800 G/1 ms, as well as the fast
Ultra-DMA interface transfer rate
of 66 MB/sec.
An advanced electromechanical
design provides exceptional
storage capacities and superior
shock ratings to improve reliability and ruggedness.
Leading-edge technology
IBM continues its tradition of mobile
storage leadership with the IBM
Travelstar 32GH, 30GT, and 20GN hard
drives. The industry’s first 4-disk 12.5 mm
mobile drive, the IBM Travelstar 32GH is
also the world’s first 32 GB notebook
hard disk drive.
The innovative hard drive design
combines IBM giant magnetoresistive
(GMR) head technology, Partial
Response Maximum Likelihood (PRML)
digital channel, a head load/unload
feature, and Enhanced Adaptive Battery
Life Extender* (ABLE) 3.0—all created
by using state-of-the-art manufacturing
techniques. This design provides the
exceptional storage capacity, performance, power management, quality,
and reliability required by today’s
notebook systems.
As a result, the new IBM Travelstar drives
are ideally suited for demanding, highcapacity Internet, digital audio, video
streaming, and real-time multimedia
applications—whether users are in the
office or on the road.
Advanced mobile systems
With these new drives, IBM has redefined
state-of-the-art storage for mobile
computing. The high speeds and
capacities of IBM Travelstar drives help
provide higher quality digital audio and
video, superior digital content creation
capabilities, and significantly faster
processing for data-intensive multimedia
and Internet applications.
By using one of the new Travelstar drives
in a laptop system, you can unchain your
multimedia lab from the desktop—
enabling high-end multimedia creativity
as mobile as your imagination.
IBM quality, support, and service
The new IBM Travelstar mobile hard drives
share common field-proven components
to provide manufacturers with superiorquality hard drives backed by a threeyear warranty and IBM technical support
and services.
Performance and reliability
The IBM Travelstar 32GH, 30GT, and
20GN hard drives use proven IBM
technology, such as IBM Drive Fitness
Test* (DFT), Self-Monitoring Analysis
and Reporting Technology (S.M.A.R.T.),
as well as a thermistor, an adaptive
control device that helps maintain high
performance and fast seek times at
high environmental temperatures.
