“The Travelstar products we have planned for 2007 give insight to what Hitachi believes are important to end-users in a mobile storage product:  ample capacity for video and other rich content, superior performance and reliability, and greater confidence in the safety of their data as users are increasingly on the move,” said Shinjiro Iwata, chief marketing officer, Hitachi Global Storage Technologies. “The 2.5-inch hard drive segment represents Hitachi’s flagship product line, and we’re working to ensure that Hitachi continues to set the pace of technology advancement for this category.”

2.5-inch Segment Acceleration

Hitachi’s new product developments will put the company in position to take advantage of IDC’s projected 22-percent compounded annual growth rate (CAGR) of the 2.5-inch segment from 2005 to 2010⁴.

“A growing number of mobile PC users are placing a high value on storage capacity, performance, reliability and security while on the go,” according to John Rydning, IDC’s Research Manager for hard disk drives. “There is a tremendous opportunity for HDD OEMs such as Hitachi to establish market leadership by delivering high capacity mobile 2.5-inch disk drives equipped with value-added features to meet these challenging requirements.”

IDC’s projection of the 2.5-inch hard drive growth shows the greatest opportunity to be in the portable PC category, followed by gaming consoles, external storage and automotive applications⁵. Hitachi participates in all of those segments and leads segment share in the portable PC category.

Hybrid: A Higher-Value Hard Drive

The hard drive industry has used low-capacity flash memory for many years to store the firmware that controls the entire hard disk drive. With the decreasing cost of flash, Hitachi believes there is greater opportunity to increase the value of hard drives by storing some system functions to flash memory rather than on the disk. The potential benefit of a hybrid storage solution – especially for mobile devices – ranges from longer battery life, faster boot-up time and recovery from hibernation, to greater reliability and higher performance.

Combined with low-cost, high-capacity storage, the hybrid solution presents a significantly higher-value hard drive, especially in mobile product segments. New 2.5-inch products shipped in 2007 will offer hybrid as an option on the same base platform.

Hard Drive Bulk Data Encryption

Today, users are able to protect their hard drive with password security, which prevents access to the drive but does not encrypt the data itself. Traditionally, for those who wished to secure their drives, the only viable solution was to use a software-based tool, which could slow down the system performance.

With the rise in notebook theft and the relative ease in which software-based password security can be compromised, Hitachi is responding with a hard-drive-level encryption solution that is virtually impenetrable. In addition, Hitachi’s introduction of full data encryption at the hardware level, allows data security to be carried out with little to no impact to system speed. Hitachi’s version of hard-drive-level data encryption scrambles data using a password-generated key as it is being written to the disk and then descrambled with the key as it is retrieved.
