Worldwide external controller-based (ECB) disk storage revenue totalled $18-billion in 2008, an 11,3% increase over 2007 revenue of $16,2-billion.

"The double-digit full year growth rate of 11,3% is all the more impressive given the current economic downturn and demonstrates the resilience of the storage industry," says Donna Taylor, principal research analyst for Gartner's global Storage Quarterly Statistics programme.
There were no market share leadership changes compared with last year. EMC maintained the top position with 25% revenue market share. IBM placed second with 13,6% and Hewlett-Packard came in third with 11,6%. Hitachi/Hitachi Data Systems placed fourth with 9,2%, followed by Dell with 8,8%. NetApp and Sun Microsystems placed sixth and seventh, respectively, with 7,8% and 5,2% market share.
Dell showed the strongest growth year-on-year at 15,5%.
In the fourth quarter of 2008, worldwide ECB revenue showed growth of 5,4%. Fifth-place Dell experienced the greatest year-over-year fourth quarter revenue growth of 11,3%.
