        MTI Technology Corp. Reports Fiscal 2005 Third Quarter
                  and Nine Months Financial Results;
      Company Increases Market Share with 86 Percent Growth Rate

    TUSTIN, Calif.--(BUSINESS WIRE)--Feb. 15, 2005--MTI Technology
Corp. (Nasdaq:MTIC), a leading multi-national total storage solutions
and services company, today announced financial results for its fiscal
2005 third quarter and nine months ended Jan. 1, 2005.
    Total revenues for the fiscal 2005 third quarter were $39.5
million, 86 percent higher than the $21.2 million reported in the
comparable prior year quarter and an increase of 25 percent over the
$31.5 million reported in the second quarter of fiscal 2005. Total
revenues for the nine-month period ended Jan. 1, 2005, grew 63 percent
to $97.1 million compared with the $59.5 million reported for the
comparable period of fiscal 2004. The third quarter of fiscal 2005
marked the Company's sixth consecutive quarter of revenue growth.
    Net product revenue for the fiscal 2005 third quarter was $29.3
million, a significant increase of 138 percent over the $12.3 million
reported in the comparable prior year quarter and 31 percent higher
than the $22.3 million reported in the second quarter of fiscal 2005.
Net product revenue for the nine-month period ended Jan. 1, 2005,
increased substantially, 116 percent, to $68.8 million compared with
the $31.8 million reported for the comparable period of fiscal 2004.
    Service revenues for the fiscal 2005 third quarter were $10.2
million, an increase of 15 percent compared with the $8.9 million
reported for the prior year quarter and 11 percent higher than the
$9.2 million reported in the second quarter of fiscal 2005. Service
revenues for the nine-month period ended Jan. 1, 2005, slightly
increased to $28.2 million from the $27.7 million reported for the
comparable period of fiscal 2004. The increase in Service revenues was
driven primarily by increasing Professional Services revenue
associated with increased product sales.
    Gross profit margin for the fiscal 2005 third quarter was 19.7
percent compared with 24.9 percent in the prior year quarter, and 22.9
percent in the second quarter of fiscal 2005. Gross profit margin for
the nine-month period ended Jan. 1, 2005, was 21.4 percent compared to
26.6 percent for the comparable period of fiscal 2004. Product gross
margins of 20.5 percent for the fiscal 2005 third quarter were at the
lower end of expectations due to a greater than normal number of
large, competitively priced transactions. Service margins were
depressed by the continued build-out of the Professional Services
organization in advance of expected higher revenues.
    As planned, operating expenses grew from $9.6 million in the prior
quarter to $11.0 million as the Company continued to expand its Sales
organization in support of its growth strategy. We expect spending
growth to moderate in the upcoming quarter.
    The Company reported results of operations for the third quarter
of fiscal 2005 compared to the same period of the prior year, as

    The Company's cash balance grew in the fiscal 2005 third quarter
due to better asset performances. As of Jan. 1, 2005, the Company had
$14.2 million in cash and cash equivalents and $10.1 million in
working capital.
    The Company also announced the closure of its Dublin, Ireland
facility, one of a combination of actions which include headcount
reductions and changes to processes and information systems. These
changes should be completed by the second quarter of fiscal 2006. When
fully in place, the Company expects improved order processing
performance with operating expenses reduced by approximately $0.7
million to $1 million per quarter. One time costs associated with the
changes are expected to be approximately $2 to $4 million.
    "We have undertaken what we consider the remaining structural
changes necessary to support the transformation of the organization
from a developer and manufacturer of data storage to a unique provider
of professional services and comprehensive storage solutions for mid-
to large-sized organizations," said Scott Poteracki, the Company's
executive vice president and chief financial officer.
    "Approximately 18 months ago, we set out an aggressive strategy to
build MTI's market share. Today we are continuing to experience solid
growth, with an 86 percent increase in revenues for the third quarter
of 2005, compared to the same period a year ago," said Thomas P.
Raimondi Jr., the Company's president and chief executive officer.
"The storage market is currently growing at approximately 10 percent
per year, while MTI is expanding at nearly eight times that rate,
having added a record number of new accounts this quarter alone. And
as we move into our new fiscal year, MTI will remain focused on
continued market share growth, while driving the Company to
profitability."
