Worldwide external controller-based (ECB) disk storage revenue totalled nearly $3,8-billion in the second quarter of 2009, a 15,7% decline from the same period in 2008, according to Gartner.

“The year-on-year double-digit decline of 15,7% primarily resulted from the economic downturn and longer sales cycles,” says Donna Taylor, principal research analyst for Gartner’s global Storage Quarterly Statistics programme. “A bright spot in the disk array market has been in network-attached storage (NAS), which experienced a 3,5% year-on-year growth rate in the second quarter of 2009.”
EMC maintained its number one position with 23,7% revenue market share. IBM placed second with 15,7%, and Hewlett-Packard came in third with 10,3% of the market. Dell placed fourth with 9,2%, followed by Hitachi/HDS with 8,7%. NetApp and Sun Microsystems placed sixth and seventh, respectively, with 8,5% and 4,5% market share.
