SimpleTech Raises Earlier Guidance for the Third Quarter of 2004 Due to

Significant Increases in Stacking Memory Business and Gross Margin

SANTA ANA, Calif., Oct. 4, 2004--SimpleTech, Inc. (Nasdaq: STEC), a designer, manufacturer and marketer of custom and open-standard memory solutions based on Flash memory and DRAM technologies, today announced updated revenue and earnings guidance for its third quarter of 2004. During its August 5, 2004 conference call announcing second quarter results, SimpleTech provided guidance that third quarter 2004 revenues would range from $60 million to $62 million. SimpleTech now expects revenues to grow sequentially by 31% to 33% from $56.5 million for the second quarter of 2004 to between $74 million and $75 million for the third quarter of 2004. SimpleTech had also provided guidance that diluted earnings per share for the third quarter of 2004 would range from $0.02 to $0.03. SimpleTech now expects diluted earnings per share of $0.05 to $0.06 for the third quarter of 2004, compared to diluted earnings per share from continuing operations of $0.02 for the second quarter of 2004.

The increased revenue and earnings guidance resulted primarily from growth in SimpleTech’s stacking memory business. The company’s stacking memory business increased approximately 97% from $17.2 million in the second quarter of 2004 to approximately $34.0 million in the third quarter of 2004. This increase was attributable to greater demand and increased market share in the server and telecom sectors. SimpleTech’s gross profit margin increased from 14.6% in the second quarter of 2004 to approximately 18.0% for the third quarter of 2004 due primarily to leveraging production resources over a larger revenue base and a more stable component pricing environment compared to the second quarter of 2004.

SimpleTech will report its actual results of operations for the third quarter of 2004 on or about November 1, 2004, after the market close. A webcast conference call will take place that same day. The call will be open to all interested investors by dial-in and through a live audio Web broadcast.
