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.
An ATA-compatible drive interface enables data transfers to 66.6+ MB/sec.
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 per- formance—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
