Worldwide External Disk Storage Systems Factory Revenue Declines for the Third Consecutive Quarter, According to IDC

(PresseBox) ( FRAMINGHAM, Mass., )
Worldwide external disk storage systems factory revenues posted a year-over-year decline of -3.5%, totaling $5.7 billion, during the third quarter of 2013 (3Q13), according to the International Data Corporation (IDC) Worldwide Quarterly Disk Storage Systems Tracker. For the quarter, the total (internal plus external) disk storage systems market generated $7.4 billion in revenue, representing a -5.6% decline from the prior year's third quarter and a seasonal sequential decline of -4.1% compared to 2Q13. Total disk storage systems capacity shipped reached nearly 8.4 exabytes, growing just 16.1% year over year.

"Despite the revenue contraction in the third quarter, we see strong demand for offerings targeted at heavily virtualized environments, such as integrated infrastructure," said Eric Sheppard, Research Director, IDC Storage. "However, this demand has been offset by several factors: reduced spending from the U.S. government, increased use of storage efficiency technologies, increased investment in public cloud capacity, and general price pressures associated with increased competitive environments."

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.
