Deskstar 75GXP - Redefining state-of-the-art for desktop storage
Leading
drive technology
The IBM Deskstar 75GXP 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. 1
