Industry-leading capacity, performance, and acoustics

IBM Travelstar 48GH, 30GN, and 15GN

2.5-inch hard disk drives

Highlights

The newest members of the
IBM Travelstar family of hard disk
drives are the first in the industry
to implement Fluid Dynamic
Bearing (FDB) motor technology
for industry-leading idle and
operating acoustic performance.
In addition, these new Travelstar
models support the fast Ultra
DMA mode-5 interface for
transfer rates of up to100 MB/sec.

The IBM Travelstar 48GH—
representing the third generation
of 5400 RPM models in the indus­try—is the highest capacity and
the highest performance mobile
drive in the industry with a
capacity of 48 GB and a maxi­mum media data transfer rate of
241 Mbits/sec for unsurpassed
capacity and performance.

The IBM Travelstar 30GN and
15GN hard drives provide areal
densities up to 25.7 Gbits/sq. in.,
yielding up to 15 GB of capacity
per disk, combined with an
industry-leading operational
shock rating of 180 G/2 ms,
which makes these drives
well suited for today’s most
demanding users.

Leading-edge technology

IBM continues its tradition of mobile
storage leadership with the IBM Travelstar*
48GH, 30GN, and 15GN hard drives. The
Travelstar 48GH—representing the third­generation family of 5400 RPM mobile
drives—is the industry’s first 48 GB
notebook hard disk drive employing four
disks in a 12.5 mm high design.

The innovative hard drive design
combines Fluid Dynamic Bearing (FDB)
motor technology, an ATA-100 interface,
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. This design provides the exceptional
quietness, storage capacity, perfor­mance, power management, quality,
and reliability required by today’s
notebook systems.

As a result, the new IBM Travelstar
drives are well suited for demanding,
high-capacity Internet, digital audio,
video streaming, and real-time multime­dia applications—whether users are in
the office or on the road.

Performance and reliability

The IBM Travelstar 48GH, 30GN, and
15GN hard drives use established IBM
technology such as TrueTrack Servo, IBM

Drive Fitness Test* (DFT), Self-Monitoring
Analysis and Reporting Technology
(SMART), as well as a thermistor, an
adaptive control device that helps
maintain high performance and fast seek
times at high environmental temperatures.

Advanced mobile systems

With these new drives, IBM has redefined
state-of-the-art storage for mobile
computing. The reduced acoustics, high
speeds and capacities of IBM Travelstar
drives support superior digital content
creation capabilities, higher quality digital
audio and video, 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 studio 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 components to
provide users and manufacturers with
superior-quality hard drives backed by a
three-year warranty and IBM technical
support and services.
