Toshiba Achieves Number One Global Market Share in Consumer Electronics Hard Disk Drive Shipments; Research Firm Reports Toshiba Holds Leadership Position for Q3 2005.

IRVINE, Calif. -- Toshiba Storage Device Division (SDD), the industry pioneer in small form factor hard disk drives (HDD), topped all HDD manufacturers in consumer electronics (CE) HDD shipments for the third quarter of 2005, according to research firm IDC. This world-leading position in CE HDD shipments is Toshiba's first, marking the company's growth and innovation with its 2.5-inch, 1.8-inch and 0.85-inch HDDs for consumer electronics and automotive applications.

According to IDC, in Q3, Toshiba had a global market share of 27.5 percent for all HDDs shipped into CE, and an impressive 43.9 percent share when excluding the 3.5-inch drive category. This leadership position underscores Toshiba's commitment to providing robust storage technology and solid execution to meet demand for key applications such as mobile PCs, GPS systems, MP3 players and automobile entertainment systems.

"This has been a landmark year for Toshiba with milestone achievements in new technologies like perpendicular magnetic recording (PMR), automotive HDDs and shipment of our 100 millionth mobile HDD," said Scott Maccabe, vice president and general manager, Toshiba Storage Device Division. "We continue to see tremendous demand for small form factor HDDs in traditional markets like mobile computing, as well as new consumer devices. Our performance in Q3 is indicative of our ability to drive adoption of leading-edge storage technologies and deliver on market demand."

Toshiba has been first-to-market on innovative mobile HDD products, including announcement and shipment of PMR drives. Toshiba's 1.8-inch PMR HDD set new records in areal density by boosting the capacity of a single 1.8-inch platter to 40 gigabytes. The company also introduced the world's smallest HDD at 0.85 inches and has led the HDD industry in pioneering storage technologies for the automotive market. Toshiba is the world's leading supplier of automotive-class HDDs with more than 80 percent market share according to TSR.

"We continue to see strong demand in the mobile HDD segment, a strategic segment for Toshiba," said Dave Reinsel, program director for storage research at IDC. "As the HDD industry becomes more competitive, the companies who will win must have both the right technology and innovations, and be able to deliver on customer demand."

Toshiba Technologies Drive New CE Devices

Toshiba's automotive HDDs can be found in on-board media centers and global positioning systems. Toshiba's 1.8-inch HDD has enabled the introduction of mobile entertainment devices, handheld computers, ultra-portable notebooks, portable handheld GPS units, MP3 players and other specialized digital products since its launch in 2000. Toshiba's 0.85-inch HDD, the first drive to provide multi-gigabyte storage capacity in a sub-one-inch form factor, will enable unprecedented functionality for next-generation mobile digital devices, including mobile phones, digital audio players, PDAs, digital still cameras, camcorders and external storage devices by providing a high-capacity storage solution in a compact design.
