According to IDC's Worldwide Quarterly Storage Software Tracker, the worldwide storage software market experienced its 14th consecutive quarter of year-over-year growth in the first quarter of 2007 with revenues of $2.7 billion, an 11.4 percent increase over the same quarter one year ago.

"Storage software continues to exhibit positive year-over-year performance, driven by growth in the archiving, replication and file system software markets and a surge in demand for storage management software," said Rhoda Phillips, research manager for storage software at IDC. "Businesses continue to implement solutions that can improve availability, recovery, and information access across heterogeneous environments."

EMC led the overall market this quarter with 25.1 percent revenue share in the first quarter of 2007. Symantec took the second position with 17.7 percent revenue share, while IBM finished in the third position with 12.3 percent revenue share.
