SIMPLETECH ANNOUNCES CLOSURE OF XIRAN DIVISION, REVISION OF REVENUE

GUIDANCE FOR THE SECOND QUARTER OF 2004, AND BOARD APPROVAL OF

STOCK REPURCHASE PROGRAM

June 16, 2004 — Santa Ana, Calif. — 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 that it has closed its Xiran Division, and has taken a one-time charge of approximately $3.5 million. As a result of this closure, SimpleTech expects to decrease operating expenses by approximately $2 million per quarter.

While the Xiran Division had successfully productized its core technology and generated nominal revenues, the time table for significant revenue realization was uncertain. Management carefully evaluated multiple alternatives for the Xiran Division. In light of the slower-than-expected maturation of the iSCSI storage market, management believed it to be in the best interests of the company to close the Xiran Division.

The company believes revenues for the second quarter of 2004 will range from $53 million to $56 million. The company is lowering its revenue guidance for the second quarter of 2004 from approximately $66 million. The revision is due primarily to a reduction of Flash sales into the retail channel and a decrease in DRAM component prices during the second quarter of 2004. Since March 31, 2004, inventory has decreased by approximately $10 million, while cash and marketable securities have increased by approximately $6 million.

Additionally, SimpleTech announced that its board of directors has authorized the company to repurchase up to $15 million of its common stock over the next 18 months. The shares may be

purchased from time to time at prevailing market prices through open market or unsolicited negotiated transactions, depending on market conditions and other considerations. There is no guarantee as to the exact number of shares that will be repurchased by SimpleTech, and the company may discontinue purchases at any time that management determines that additional purchases are not warranted. Repurchased shares would be returned to the status of authorized but un-issued shares of common stock. As of March 31, 2004, SimpleTech had approximately 48 million common shares outstanding.
