Hitachi GST Unleashes Ultra Fast Half Terabyte Mobile Hard Disk Drive

New 7200 RPM Travelstar Drive Delivers High Capacity and Industry-Leading
Performance with Eco-Friendly Features; Optional Data Encryption Helps Keep Data
Safe and Secure
SAN JOSE, Calif.--(Business Wire)--
Building on years of innovation, Hitachi Global Storage Technologies (Hitachi
GST) today announced that is it shipping its fifth-generation, 7200 RPM mobile
hard disk drive. The Hitachi® Travelstar 7K500 is a 500GB, 2.5-inch, 3Gb/s SATA
drive designed for notebooks, gaming systems and professional external storage
solutions. Combining leadership performance, ruggedness and capacity, Travelstar
7K500 is ideal for multitasking, gaming and other graphic-intensive
applications. The new Travelstar 7K500 is the fastest hard drive in its class
and delivers up to 56 percent higher capacity and 16 percent better application
performance than its predecessor1. It also provides best-of-breed operating
shock and outstanding power management for sturdy, unplugged notebook
performance.

"Portable PC shipment growth continues to be one of the most significant market
drivers underpinning 2.5-inch disk drive demand, and is a major reason why IDC
expects the 2.5-inch mobile HDD market will grow at a 16.8 percent 2008-2013
compound annual growth rate," said John Rydning, research director for hard disk
drives at IDC. "Hitachi`s new 500GB mobile 2.5-inch HDD with a 7,200 rpm
spin-speed provides PC OEMs an opportunity to differentiate PCs with both
capacity and performance."

Meeting Standards for Mobile Security

Due to their value and portability, notebooks and external storage devices are
highly susceptible to theft. If those devices fall in the wrong hands, sensitive
data stored on the drive could become compromised. To help combat this issue,
Hitachi GST has been providing hardware-based Bulk Data Encryption (BDE) as an
option on its Travelstar mobile hard drives for four generations. Travelstar
7K500 is one of the first mobile drives to be compliant with the Trusted
Computing Group`s (TCG) Opal storage security specification, a new open standard
designed to strengthen data protection and safeguard notebooks in the event of
system loss or theft.

When the Hitachi BDE option is enabled, the hard drive will encrypt all data
that comes from the system as it is written to the media. When read back, the
drive decrypts the data so that it can be understood by the system. Since the
hard drive is doing the encryption work, there is no impact on system
performance. A Hitachi hard drive with BDE is always automatically encrypting
data, so the system user never has to worry about whether or not the data is
being protected. For commercial or corporate IT managers with a large pool of
systems, BDE also speeds up and simplifies the drive re-deployment process. By
deleting the encryption key, the data is rendered unreadable, thereby
eliminating the need for time-consuming data-overwrite.

following videocast.

"With Hitachi`s support for the TCG Opal specification, we`re working with
industry leaders who are enabling more widespread adoption and interoperability
across the entire storage ecosystem," said Brendan Collins, vice president of
Product Marketing at Hitachi Global Storage Technologies. "With the launch of
the Travelstar 7K500, Hitachi continues to solidify its position as the segment
and technology leader in this space."

Low-Power Performer

Travelstar 7K500 has been designed for energy efficiency with superior low power
consumption at 0.69 watts idle power and 1.8 watts during read/write operations,
which contributes to longer battery life in notebooks and other mobile
applications. The Travelstar 7K500 is also the latest drive to be distinguished
by the Hitachi EcoTrac classification due to its low power, halogen-free design,
RoHS compliance and steps in eco-friendly product design, manufacturing,
operation and disposal.

Availability

Travelstar 7K500 is now shipping in limited quantities to top tier OEMs. Volume
shipments will begin this month. Capacities include 120GB, 160GB, 250GB, 320GB
and 500GB. Hitachi will offer an enhanced-availability (EA) version, available
in 160GB to 500GB capacities in November `09. The EA version is specifically
designed for applications requiring 24x7 operation in lower transaction
environments, such as blade servers, network routers and surveillance systems.
