EMC Corporation, the world leader in information management and storage, extended its market share position in worldwide revenue for External Disk Storage systems for the eighth consecutive quarter in the second fiscal quarter of 2005, according to a new report from IDC (a).

In NAS, #1 EMC widened its lead over #2 Network Appliance to five percentage points in the second quarter, growing its quarterly revenue share to more than 40%.

Howard Elias, EMC Executive Vice President, Corporate Marketing and Office of Technology, said, "Unmatched innovation and choice continues to win over customers determined to improve the protection, security, movement and intelligent management of their information. During the second quarter, organizations invested in our broadening product portfolio to advance their information lifecycle management strategies. The investments we are making abroad again paid off during the quarter, as EMC expanded its lead in Western Europe and Asia Pacific, and advanced our market position in Japan.

"NAS continues to be a very positive story for EMC," continued Elias. "EMC Celerra platforms delivered NAS revenue growth at more than twice the rate of our closest competitor during the second quarter, as customers continued to invest in our high-performing and functionality-rich solutions for file-based information management and storage."

"Our partners also continued to contribute to our overall success, delivering our expanding line to new customers around the globe," commented Elias. "Combined, sales from EMC and co-branded Dell/EMC external disk storage systems represented nearly a third of the total External Disk Storage market in the second quarter and almost half of its growth."
