STAMFORD, USA: Worldwide external controller-based (ECB) disk storage revenue totaled nearly $3.8 billion in the second quarter of 2009, a 15.7 percent decline from the same period in 2008, according to Gartner Inc.

Donna Taylor, principal research analyst, global storage quarterly statistics program, Gartner, said: “The year-over-year double-digit decline of 15.7 percent primarily resulted from the economic downturn and longer sales cycles. A bright spot in the disk array market has been in network attached storage (NAS), which experienced a 3.5 percent year-over-year growth rate in the second quarter of 2009.”

EMC maintained its No.1 position with 23.7 percent revenue market share. IBM placed second with 15.7 percent, and Hewlett-Packard came in third with 10.3 percent of the market. Dell placed fourth with 9.2 percent, followed by Hitachi/HDS with 8.7 percent. NetApp and Sun Microsystems placed sixth and seventh, respectively, with 8.5 percent and 4.5 percent market share.
