Industry-leading capacity, performance, and acoustics
in a low-profile hard drive
Hitachi Travelstar 40GNX 2.5-inch
hard disk drive
Highlights
Hitachi offers models that operate with the Enhanced Availability feature
40GNX—the fifth generation of 5,400rpm models—offers high capacity and high performance in the
industry with a 40GB , 9.5mm hard drive.
40GNX provides areal densities of up to 34Gbits/sq.inch, yielding up to 20GB of capacity per disk
All models contain Fluid Dynamic Bearing (FDB) motor technology for industry-leading idle and operating
acoustic performance

Leading-edge technology
The HitachiTravelstar 40GNX is a 9.5mm
high, fifth generation 5400 rpm, hard disk
drive for mobile computing.
The innovative hard drive design
combines AFC Media, Fluid Dynamic
Bearing (FDB) motor technology, Giant
Magnetoresistive (GMR) heads, Partial
Response Maximum Likelihood (PRML)
digital channel, head load/unload tech-
nology, Enhanced Adaptive Batter Life
ExtenderTM (ABLE) 3.0, and an ATA/100
interface. With this design, the Travelstar
40GNX provides exceptional storage
capacity, performance, power manage-
ment and quality required by today’s
demanding notebook requirements.
The Travelstar family of hard disk drives
incorporates the latest in storage
technology—Antiferromagnetically-cou-
pled (AFC) media, informally known as
“pixie dust.” This technology sandwiches
a three-atom-thick layer of ruthenium, a
precious metal, between two magnetic
layers on a disk, allowing for a higher areal
density, breaking through limitations of the
super paramagnetic effect.
As a result, the Hitachi Travelstar drives
are suitable for demanding, high-capacity
Internet, digital audio, video streaming,
and real-time multimedia applications—
whether users are in the office or on
the road. In non-traditional applications,
Travelstar drives can now incorporate into
such products as Point-of-Sale Systems,
Set-Top Boxes, Telemetry (automobile)
applications, and communications and
entertainment systems.
Performance and reliability
The HitachiTravelstar 40GNX hard drive
uses proven storage technologies such
as TrueTrack Servo, Drive Fitness Test™
(DFT), and 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 tem-
peratures.
Enhanced Availability models
Hitachi also offers enhanced availability
features on selected new Travelstar mod-
els. These industry-first models increase
the hard disk drive’s available “power-on”
hours for emerging applications with con-
tinuous operation. At a read/write or data
access rate of up to 50 percent—a typical
usage cycle for 24x7 blade server environ-
ments—the drives are designed to allow
users to leave these drives powered on
around-the-clock.
Advanced mobile systems
The Travelstar 40GNX redefined state-
of-the-art storage for mobile computing.
