Worldwide external controller-based (ECB) disk storage revenue totalled $4,5-billion in the second quarter of 2008, an 18,8% increase over the same period in 2007.

According to Gartner, EMC maintained the top spot overall, finishing the quarter at 24,3% market share. IBM was in second place with 14,1% of the market followed by Hewlett-Packard with 11,8%.
Sun Microsystems showed the highest growth year-over-year at 34,7% mainly due to a large increase in the company's Sun StorageTek 2000, 6000 and 9000 series revenue. NetApp had the next highest growth with 22,9%. Also recording double-digit growth were Dell with 18,3%, Hitachi Data Systems at 18,1%, EMC at 16%, and IBM with a growth of 14,9%.
On a regional basis, Japan showed the highest growth at 38,7% year-over-year followed by Latin America, Europe Middle East and Africa, and Asia/Pacific at 25,2%, 22,3% and 16,6%, respectively. Growth in North America for the same period was 12,7.
"Although growth in North America was lower than the other regions it was still very respectable at almost 13% given the current economic conditions," says Robin Burke, research vice-president for Gartner's global Storage Quarterly Statistics programme.
