Worldwide external disk storage systems factory revenues posted year-over-year growth of 12.2%, totaling just over $5.6 billion, in the second quarter of 2011 (2Q11), according to the International Data Corporation (IDC) Worldwide Quarterly Disk Storage Systems Tracker. For the quarter, the total disk storage systems market grew to just shy of $7.5 billion in revenues, representing 10.2% growth from the prior year’s second quarter. Total disk storage systems capacity shipped reached 5,353 petabytes, growing 46.7% year over year.

“External storage systems revenue increased solidly in the second quarter, with all the segments experiencing double-digit gains as end-user investment in new technology continued,” said Liz Conner, senior research analyst, Storage Systems. “New vendor offerings around virtualization, Big Data, and Cloud computing coupled with less restrictive IT budgets have contributed to this growth.”

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.
