| Highlights
Industry leading performance
Offering the first 3.2 and 4.0 GB capacities in the
industry standard 12.5mm profile, Travelstar 4GT provides
storage solutions for mobile and network connected
applications. Performance enhancements include increased
data buffer size (now 512KB), a new Interface Transfer
Rate of 33.3 MB/sec, and the industry's first mobile
implementation of the Ultra DMA /33 interface.
Improved power management
IBM's proven Enhanced Adaptive Battery Life ExtenderTM 2.0
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.
Superior durability
The new Travelstar 4GT extends the proven Travelstar
ruggedness to now withstand up to 600 G/2 ms non-operating
shock and 100 G/2 ms operating shock, without sacrificing
performance or reliability.
Leading drive technology
The Travelstar 4GT achieves its capacity, performance, and
low-power management capabilities by employing IBM's
development and integration experience in advancing disk
drive technology. These include IBM's advanced head
technology, Magnetoresistive Extended (MRX), NO-ID(TM)
sector formatting, Partial Response Maximum Likelihood (PRML)
digital channel, and S.M.A.R.T. (Self Monitoring Analysis
and Reporting Technology) protocol.
MRX advanced head technology offers increased areal
density, reducing the number of disks and heads required.
Load/Unload technology allows the Travelstar 4GT to fly
these heads closer to the disk surface, improving areal
density and performance. No-ID sector formatting increases
storage capacity by eliminating the overhead caused by the
duplicate storage of each data sector's ID fields,
resulting in more disk space for a customer's data. The
PRML digital channel allows higher areal densities and
significantly contributes to the overall performance of
the drive. S.M.A.R.T. protocol support protects data
availability and alerts a system of impending drive
failure.
The combination of IBM's leading technologies with the
proven mechanical design of Travelstar 4GT provides a new
high capacity, high performance, and low power dissipation
benchmark for today's notebook operating systems.
Travelstar enables more availability of local and remote
network resources, such as the Internet, with laptop
applications.
Interface
The Travelstar 4GT 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 an array of technical support,
qualification support, and integration assistance. This
comprehensive support package is designed to ensure that
IBM customers can continue to develop and manufacture
high-quality, cost-effective systems.
