IDC Sizes Up Disk Storage

FRAMINGHAM, Mass. -- Worldwide external disk storage systems factory revenues grew $239 million in the first quarter of 2007 (1Q07), posting 5.9% growth from a year ago to $4.3 billion, according to the IDC Worldwide Quarterly Disk Storage Systems Tracker. For the quarter, the total disk storage systems market grew to $6.1 billion up 7.2% from the prior year's first quarter. Total disk storage systems capacity shipped surpassed 1,000 petabytes for the second consecutive quarter, growing 60.4% over the first quarter of 2006.

"External storage systems selling under $50,000 drove the growth in the first quarter of 2007," said Brad Nisbet, program manager, IDC Storage Systems. "After several quarters of impressive growth in 2006 for midrange and high-end systems selling with average prices above $50,000, we saw only modest gains in these systems this quarter. The growth in lower-end products indicates opportunity across the board as customers continue to invest in a broad spectrum of available storage solutions."
