High-Performance and High-Value Storage Solutions for Mobile Computing

As notebook and ultra-portable computers become more powerful, more is being expected of them, and more is riding on the performance, capacity, and reliability of their data storage capabilities. Significant advances in multimedia applications, network computing, the Internet, and other forms of online communication have stretched the boundaries of mobile computing.

4.4 and 5.1 GB Full Height Disk Drives

Increased capacity and enhanced performance create a storage solution for true desktop equivalency in a mobile computer

Desktop equivalency
The highest storage capacity of 5.1 GB and superior drive technology for high performance provides desktop equivalency in notebook computing to meet the most demanding requirements of data intensive applications.

Performance leader
Fast access rates to large amounts of data, demanded by integrated image, video, Internet and multi-media applications are provided by Travelstar 5GS’ media transfer rates.

Performance enhancements include increased data buffer size (now 512 KB) and the first mobile drive implementation of Ultra DMA/33, improving the Interface Transfer Rate to 33.3 MB/sec.

Improved power management
Enhanced Adaptive Battery Life Extender^(TM) 2.0 power management technology 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.

Data protection
S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology) protocol support protects data availability and helps alert a system of impending drive failure.

Leading drive technology

Travelstar 5GS meets the demands of notebook and subnotebook users by employing technology innovated and developed by IBM. These include IBM’s advanced Magnetoresistive Extended head technology (MRX) , Load/Unload, NO-ID ^(TM) sector formatting, Partial Response Maximum Likelihood (PRML) digital channel and Enhanced Adaptive Battery Life Extender 2.0 technology.

MRX advanced head technology offers increased areal density, reducing the number of disks and heads required. Load/Unload technology enables the use of smooth disks, allowing lower Fly Height, resulting in improved 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 and instead, uses that disk space for a customer’s data. The PRML digital channel allows higher areal densities, significantly contributing to the drive’s overall performance.

Combining IBM’s advanced technologies allows Travelstar 5GS to achieve new high capacity, high performance, and low power dissipation required by today’s high-end notebook operating systems and data-intensive applications.

Interface

The Travelstar 5GS 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.
