02 Dec 2011 

FRAMINGHAM, Mass., December 2, 2011 – Worldwide external disk storage systems factory revenues posted year-over-year growth of 10.8%, totaling just under $5.8 billion, in the third quarter of 2011 (3Q11), according to the International Data Corporation (IDC) Worldwide Quarterly Disk Storage Systems Tracker. For the quarter, the total disk storage systems market grew to $7.6 billion in revenues, representing 8.5% growth from the prior year's third quarter. Total disk storage systems capacity shipped reach 5,429 petabytes, growing 30.7% year over year.

"The third quarter of 2011 was a strong quarter for Enterprise Storage, posting solid growth in factory revenue and signaling a return to 'business as normal'," said Liz Conner, senior research analyst, Storage Systems. "The trend of increased spending during the economic recovery period, specifically on high-end systems, has started to draw to a close. As IDC predicted, year-over-year growth has started to slow and is now approaching pre-economic crisis levels."

Taxonomy Notes:

IDC defines a Disk Storage System as a set of storage elements, including controllers, cables, and (in some instances) host bus adapters, associated with three or more disks. A system may be located outside of or within a server cabinet and the average cost of the disk storage systems does not include infrastructure storage hardware (i.e. switches) and non-bundled storage software.

The information in this quantitative study is based on a branded view of the disk storage systems sale. Revenue associated with the products to the end user is attributed to the seller (brand) of the product, not the manufacturer. Original equipment manufacturer (OEM) sales are not included in this study. In this study, Hitachi Data Systems (HDS) sales do not reflect their OEM sales to Sun Microsystems and Hewlett-Packard.

IDC's Worldwide Disk Storage Systems Quarterly Tracker is a quantitative tool for analyzing the global disk storage market on a quarterly basis. The Tracker includes quarterly shipments and revenues (both customer and factory), Terabytes, $/Gigabyte, Gigabyte/Unit, and Average Selling Value. Each criteria can be segmented by location, installation base, operating system, vendor, family, model, and region.
