Bigger Drives and Increased Fragmentation Cause Diskeeper Sales to Soar.

BURBANK, Calif. -- Diskeeper Corporation announced its highest ever second-quarter of volume license sales. The last quarter brought current Diskeeper sales to over 17 million licenses sold and Diskeeper is on track for unprecedented volume license sales in 2005. This increased demand is a reflection of a new high capacity storage environment where fragmentation is more of an issue than it ever has been.

Diskeeper is the technology leader in automatic defragmentation and the most highly awarded system tool of its kind -- with a record 231 awards and editor accolades received in 2004 alone and already over 100 awards received in 2005. According to NPD Group, Diskeeper dominates the enterprise market accounting for 95 percent of standalone defragmenter sales through distribution. Diskeeper is the Number One Automatic Defragmenter(TM), consistently employing the most cutting-edge technology such as Smart Scheduling, I/O Smart, and a Terabyte Volume engine specifically designed for enterprise systems.

According to Executive Vice President Manny Salinas, "As hard drives are getting larger, fragmentation is more of an issue now than it has ever been before. Even more corporate sites are turning to Diskeeper to defragment daily for maximum system performance."
