SAN JOSE, Calif. - 27 Mar 2001: IBM today announced the world's quietest family of mobile hard disk drives including the industry's highest capacity notebook drive. With reduced noise levels, faster speeds and higher performance, IBM's new Travelstar family provides the optimal storage solution for data, music, video, digital photo and streaming media.

Incorporating IBM's Drive Noise Suppression System (DNSS) across its entire product line, the new Travelstar drives offer significantly reduced noise levels that enhance the user's experience while enjoying music and video on the notebook computers. DNSS replaces the traditional ball bearing design with the fluid dynamic bearing spindle motor technology and voice coil motor dampening enhancements. These efforts result in acoustical noise reduction, improved shock tolerance and superior reliability.

Featuring the industry's highest capacity notebook drive at 48 GB, the Travelstar 48GH, allows individuals to store 48,000 high-resolution photographs, 74 musical CDs, 48,000 paperback novels or 12 DVD movies.* The Travelstar 48GH stores five times as much data as today's average notebook hard drive and 50 percent more than IBM's previous largest mobile drive, the Travelstar 32GH, the industry's current capacity leader.

While most mobile drives spin at 4,200 rotations per minute (rpm), the Travelstar 48GH spins at 5,400 rpm, making it the fastest mobile hard disk drive on the market. Additionally, with media transfer rates up to 241 megabits per second (Mbits/sec), the Travelstar 48GH combines spindle speed and improved processing speed to boost its overall performance. The new drives also are more power efficient, increasing capacity and speed while maintaining the energy requirements of the previous product generation.

The new family of mobile drives are Travelstar 48GH, 30GN (available in 30 and 20 GB capacities) and 15GN (available in 15, 10 and 6 GB capacities) models. The 30GN and 15GN offer improvements in both performance and acoustics. In fact, the Travelstar 15GN is quieter during its read/write operation than its predecessor is while idling.

"IBM remains the worldwide leader as the number one supplier in mobile hard disk drives," said Bill Healy, vice president, IBM Storage Technology Division.
"Our new Travelstar family -- providing the highest capacity, fastest speed, quietest environment and improved performance -- redefines industry standards in innovation."

IBM holds the market leadership in the mobile hard disk drive business with 41 percent of volume shipments worldwide in the fourth quarter of 2000, according to a recent International Data Corporation report.

"With 90 percent of all storage capacity residing in the hard drives of individual desktop PCs, IBM's mobile drives are likely to dwell in our homes and offices," said J. Gerry Purdy, president & CEO of Mobile Insights, Inc. "With low acoustics, high capacity and fast seek time, the new Travelstar products will definitely enhance the way we live, work and play in this digital age."

In addition to the DNSS acoustical advantage, each new Travelstar drive incorporates glass disk platters, an ATA-100 interface, giant magnetoresistive recording heads, Partial Response Maximum Likelihood digital channel, load/unload technology and an Enhanced Battery Life Extender 3.0. These key features contribute to higher capacity, better performance and increased reliability. IBM achieves these improvements while minimizing power requirements to maximize battery life in notebook applications.

IBM plans to ship these new hard disk drives in the second quarter of 2001 to all leading notebook manufacturers worldwide, including Compaq Computer Corporation, Dell Computer Corporation, Hewlett-Packard and, of course, IBM.

"HP's notebook users are increasingly producing and using rich multimedia content. As their mobile storage needs have grown, this has created a need for more reliable and quieter high-capacity disk drives," said Paul Morgan-Witts, director of Product Marketing for HP's Mobile Computing Division. "HP is addressing our customers' need for reliable mobility through the use of advanced technology such as the newest IBM Travelstar mobile disk drives, which offer increased durability and improved acoustics."

"As the world becomes more mobile and the amount of multimedia content increases, users are looking for faster, more powerful ways to manage and store that wealth of information," said Leo Suarez, director of worldwide product marketing, mobiles, IBM Personal Computing Division. "Travelstar hard drives are currently used on ThinkPads such as our new ThinkPad A22P, and we plan to use this latest Travelstar drive on a variety of future IBM notebooks, providing our customers with a high-performance storage solution for video, audio, data, and other rich content."

IBM invented and shipped the first hard disk drive in 1956. In 2000, the company received the National Medal of Technology, the highest honor the President can bestow on leading innovators, in recognition of IBM's leadership in developing and commercializing data storage technology.
