SANTA CLARA, Calif. -- Hitachi Data Systems (HIT):

WHO: Executives of Hitachi Data Systems Corporation, a wholly
    owned subsidiary of Hitachi, Ltd. (NYSE:HIT), and Tony Asaro,
    senior analyst for the Enterprise Strategy Group (ESG).

    WHAT: Following the success of the company's first Virtualization
    Roadshow earlier this year, Hitachi Data Systems is again
    partnering with TechTarget to sponsor the second edition -- a
    three-city tour, including stops in Toronto, Washington, DC, and
    Los Angeles. The topic is, "Building an Effective Tiered Storage
    Strategy Through Virtualization." This seminar will feature a
    presentation by Tony Asaro, a leading industry analyst, discussing
    the technology, benefits, and capabilities of storage
    virtualization. Speaking for Hitachi Data Systems will be Lewis
    Winning, Vice President of Global Sales Operations, who will
    expand on the company's approach to these methodologies and how
    customers can benefit from their implementation.

    WHEN AND WHERE:

        November 17, 2005 --  Toronto, Canada

        December 6, 2005  --  Washington, DC

        December 13, 2005 --  Los Angeles, CA

    WHY: Storage virtualization is a rapidly emerging solution to help
    customers simplify data and storage management, control
    administration costs, reduce hardware and software spending and
    better utilize their storage assets. The purpose of this seminar
    is to demonstrate the benefits that virtualization and tiered
    storage can bring to companies that want to achieve these results.
    The first edition of the Virtualization Roadshow, held earlier
    this year in five cities -- including New York, San Francisco,
    Atlanta, Chicago, and Dallas -- was met with tremendous positive
    response from Hitachi Data Systems customers and partners.
