Worldwide External Disk Storage Systems Factory Revenue Declines for the First Time Since 2009, According to IDC

FRAMINGHAM, Mass., June 7, 2013 – Worldwide external disk storage systems factory revenues posted a year-over-year decline of -0.9%, totaling just over $5.9 billion, in the first quarter of 2013 (1Q13), 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 $7.7 billion in revenue, representing a decline of -3.2% from the prior year's first quarter. Total disk storage systems capacity shipped reached 7.8 exabytes, growing 26.4% year over year.

"Reduced demand within developed markets caused global sales of external disk systems to fall slightly during the first quarter of 2013," said Eric Sheppard, Research Director, Storage. "Emerging markets drove growth within the global market but this was not enough to offset declines elsewhere. Independent storage suppliers were better positioned to capitalize on this new level of demand than their competitors, some of whom are currently working through product transitions and declining server sales."

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.
