   MTI Technology Corporation Reports Fiscal 2005 Second Quarter &
                     Six Months Financial Results;
              Revenues Surge 54 Percent from Prior Year

    TUSTIN, Calif.--(BUSINESS WIRE)--Nov. 15, 2004--MTI Technology
Corporation (NASDAQ:MTIC), a multi-national total storage solutions
and services company, today announced financial results for its fiscal
2005 second quarter ended October 2, 2004.
    For the second quarter of fiscal 2005, the Company reported total
revenues of $31.5 million, an increase of 54 percent compared to $20.5
million in the same quarter of the prior year, and an increase of 21
percent compared to $26.0 million in the prior quarter. Product
revenue for the second quarter 2005 was $22.3 million, an increase of
99 percent compared to $11.2 million in the same quarter of the prior
year, and an increase of 30 percent compared to $17.2 million in the
prior quarter. Service revenues for the second quarter 2005 were $9.2
million compared to $9.3 million in the same quarter of the prior
year, and compared to $8.8 million in the prior quarter. Product gross
margins were 25 percent. Service gross margins were 18 percent as
compared to 30 percent in the same period of the prior year, as we
invested in growing our professional services organization, ahead of
expected revenue growth. Expenses grew 24 percent from the most recent
quarter as the Company executed its growth strategy with the addition
of sales personnel.
    "MTI continues its dramatic growth with revenues increasing for
the fifth consecutive quarter and product revenue doubling over the
past year. This is particularly rewarding as our growth substantially
outpaces the storage market which clearly demonstrates that our
strategy is working," said Tom Raimondi, MTI president and chief
executive officer. "This is clear validation that our continued
commitment will enable us to be one of the industry's leading
multi-national data storage management integrators."
    The Company reported results of operations for the second quarter
of fiscal 2005 as follows (in thousands, except per share data):
