IDC Finds Strong Demand for Archiving and Data Protection and Recovery Software Driving Market Growth in the Third Quarter of 2007

FRAMINGHAM, MA – December 10, 2007 – According to IDC’s Worldwide Quarterly Storage Software Tracker, the worldwide storage software market experienced its 16th consecutive quarter of year-over-year growth in the third quarter of 2007 with revenues of $2.8 billion, a 9.8% increase over the same quarter one year ago.

“Overall market growth was driven by strong performance in both the archiving and data protection and recovery markets,” according to Michael Margossian, research analyst, Storage Software at IDC. “Customer demand for storage replication seems to be cooling off, while the need for archiving appears to be picking up.”

The archiving market grew 13.6% year over year, driven by e-discovery, regulatory compliance, and overall storage optimization needs. Data protection and recovery, while down from 2Q07, had strong year-over-year growth of 13.1%. This growth was perpetuated by five out of the top six vendors having double-digit growth over 3Q06.

EMC led the overall market with 25.6% revenue share in the third quarter of 2007. Symantec took the second position with 17.0% revenue share, while IBM finished in the third position with 12.4% revenue share. Network Appliance finished in the fourth position with 10.9% revenue share. Again, CA and HP rounded out the top 5 in a statistical tie, with both having a 4.3% revenue share.
