IDC: External Disk Systems Climb

FRAMINGHAM, Mass. -- According to the IDC Worldwide Quarterly Disk Storage Systems Tracker, worldwide external disk storage systems factory revenues in the second quarter of 2007 grew 6.2% from a year ago to $4.3 billion, marking 18 consecutive quarters of year-over-year growth. For the quarter, the total disk storage systems market grew to $6.1 billion up 5.9% from the prior year's quarter. Total disk storage systems capacity shipped grew 50.1% from a year-ago quarter, reaching 1.2 exabytes.

"We continue to see a lull in high-end spending in the second quarter of 2007, particularly on external storage systems selling over $300,000," said Brad Nisbet, program manager, IDC Storage Systems. "2006 proved to be an impressive year of spending among large organizations looking to achieve datacenter consolidation, especially in the U.S. With many large customers easing back on the purchase of additional capacity in the first half of 2007, disk storage systems vendors with a diversified portfolio of products and broad bases of customers will be best positioned to overcome the varying patterns in spending."
