Worldwide external controller-based (ECB) disk storage revenue totalled $3,8-billion in the first quarter of 2009, an 11,1% decline from the same period in 2008, according to Gartner.

"The year-over-year double-digit decline of 11,1% primarily resulted from the economic downturn and longer sales cycles," says Donna Taylor, principal research analyst for Gartner's global Storage Quarterly Statistics programme.
There were no market share leadership changes compared with the first quarter of last year. EMC maintained its Number one position with 23,2% revenue market share. IBM placed second with 11,1%, and HP came in third with 9,8%. Hitachi/Hitachi Data Systems placed fourth with 10,6%, followed by Dell with 9,2%. NetApp and Sun
Microsystems placed sixth and seventh, respectively, with 8,5% and 4% market share.
