Toshiba Extends PMR to 2.5-Inch HDD Family with 200GB Market-Leading Capacity; World's Highest Areal Density Enables First 100GB-Per-Platter Mobile HDD

Business Wire, June 5, 2006

IRVINE, Calif. -- Toshiba Storage Device Division (SDD), the industry pioneer in small form factor hard disk drives (HDDs), today introduced a 200GB 2.5-inch HDD based on advanced Perpendicular Magnetic Recording (PMR) technology. Toshiba's second-generation PMR offering features the world's highest areal density at 178.8 gigabits per square inch and the highest capacity in the standard 9.5mm mobile PC format.

The 200GB dual-platter MK2035GSS is Toshiba's first PMR drive to incorporate tunnel magneto-resistive recording (TMR) head technology. Toshiba's new 2.5-inch HDD is light weight at 98 grams and incorporates the Serial ATA (SATA) II interface with native command queuing, enabling faster data transfer rates and improved technical performance.

"As a leading partner for mobile PC manufacturers, we've listened to our customers' needs for high-capacity storage in a small form factor to enable the advanced multimedia applications and enriched usage experience that consumers are demanding today," said Scott Maccabe, vice president and general manager, Toshiba SDD. "Our technology innovation in PMR has laid the foundation for delivering the industry's highest capacity and areal density in the standard mobile drive form factor. It's a win-win combination for mobile PC manufacturers who want to differentiate their offerings with features that attract high-end consumers."

Using Toshiba's 200GB 2.5-inch HDD, mobile PC manufacturers can create value with end consumers by providing enough capacity for gaming, video, music and other multimedia applications, positioning these mobile PCs as viable desktop replacement options.

Toshiba is the industry leader in mobile HDD shipments (2.5 inch or smaller form factors) with a 29 percent market share, according to research firm IDC. The company has held that position since Q3 of 2005.

Toshiba will start mass production for the 2.5-inch 200GB MK2035GSS HDD in August 2006. The company will showcase the new HDD at Computex in Taipei, Taiwan, June 6-10, 2006, in booth #B624. For more information about Toshiba's line of 2.5-inch HDDs, visit www.sdd.toshiba.com.
