Redefining state-of-the-art for desktop storage

IBM Deskstar 75GXP and Deskstar 40GV
hard disk drives

Highlights

The IBM Deskstar* 75GXP com­bines industry-leading perfor­mance at 7200 RPM with internal
transfer rates of 444 Mb/sec and
average seek times of 8.5 ms to
enable a sustained data transfer
rate of up to 37 MB/sec. Capaci­ties range from 75 to 15 GB.

The IBM Deskstar 40GV balances
capacity, performance, and price
with one and two disks, 5400 RPM,
and an average seek time of 9.5
ms in capacities of 40 to 20 GB.

A safety ramp feature virtually
eliminates damage to the data
area caused by drive mishandling
before installation.

A thermal monitor protects data
writes/reads over the full system
temperature range.

Tagged command queuing and
hardware caching boost sus­tained data rates to reduce wait
times.

Leading drive technology

The IBM Deskstar 75GXP and Deskstar
40GV disk drives combine the perfor­mance and capacity to handle a wide
range of advanced desktop and audio/
video applications. The IBM Deskstar
75GXP incorporates innovative new tech­nologies to greatly enhance system per­formance—delivering an internal transfer
rate that tops the industry average by
27 percent. Glass media, differential
preamplifier, and fifth generation GMR
heads enable this level of performance
by increasing track capacity an average
of 41 percent. A thermal monitor helps
ensure data reliability at this high rate.

The industry’s greatest areal densities
provide popular capacity points while
reducing the number of components
and increasing reliability. The first desktop
drive with the IBM safety ramp feature
(head load/unload capability) helps
protect data by moving the heads off the
media surface when powering down. In
addition, a laminated top cover and
ceramic spindle bearings reduce drive
acoustics by up to 7 dB.

IBM Deskstar drives utilize proven IBM
technologies such as TrueTrack* servo
and No-ID* sector formatting. IBM Drive
Fitness Technologies, a set of diagnostic
tools, include award-winning Drive
Fitness Test* (DFT), S.M.A.R.T. Self Test,
and error logging.

Advanced desktop systems

With these new drives, IBM has redefined
state-of-the-art for storage. The fast speeds
and high capacities of IBM Deskstar
drives translate into higher quality digital
audio and video, superior digital content
creation capabilities, and significantly
faster processing for data-intensive
multimedia and Internet applications.

IBM quality and service

IBM drives are backed by an array of
technical support and services, which
may include customer and integration
assistance.
