New 2.5-inch up to 1 TB and 3.5-inch 4 TB Hard Drives Optimized for Small NAS Systems Expand WD's Power of Choice

IRVINE, Calif. – Sept. 3, 2013 – WD®, a Western Digital (NASDAQ: WDC) company and storage industry leader, today announced the expansion of its category leading WD® Red™ NAS line of SATA hard drives specifically designed for home and small office NAS (network attached storage) systems with one to five drive bays. Powered by NASware™ 2.0 technology, WD Red is compatibility-tested with top NAS system manufacturers and optimized for performance and reduced power consumption. WD Red hard drives are now available in a 2.5-inch form factor with 1 TB and 750 GB capacities and a new 3.5-inch 4 TB capacity.

"WD led the category in developing hard drives specifically built for small NAS environments with the WD Red product line to service the unique environment of NAS and the growing demand for affordable, reliable, and compatible storage," said Matt Rutledge, vice president of client storage systems for WD. "Through dialogue with our NAS partners and customer advocacy for WD Red, we saw the need for additional capacity in the 3.5-inch form factor with our new 4 TB offering, but we also wanted to deliver a highly reliable and compatible 2.5-inch hard drive built specifically for small NAS. This small form factor enables our customers to use high capacity NAS hard drives that offer performance, quiet operation, and low power consumption in a more compact NAS enclosure. We see an opportunity for growth in smaller footprint NAS systems, media players and other industrial applications. WD's pride is in its product and our vision is shared with our customers."

Top industry analysts see NAS continuing to represent one of the fastest-growing segments of the worldwide SOHO storage systems market. From both the revenue and terabyte perspectives, spending on NAS will continue to experience strong growth through the forecast period (to 2015), driven by a major shift of storage deployments toward IP-connected systems. (Worldwide Personal and Entry Level Storage Tracker IDC 2013).

The next generation of WD Red hard drives deliver the best NAS experience for WD customers with massive capacity and a new version of NASware™ 2.0, which further improves drive reliability and protects customer data in the event of a power loss or disruption. WD Red hard drives also feature 3D Active Balance Plus™, an enhanced balance control technology, which significantly improves overall drive performance and reliability. Exclusive for WD Red customers, WD also offers free premium 24x7 dedicated phone support and a three-year limited warranty.

The addition of new form factor and capacity WD Red hard drives further underscores WD's "Power of Choice" mission for client hard drive solutions. WD recognizes the diverse challenges of customers and their applications and strives to empower them with storage solutions tailored to best suit their specific needs.

Integrating seamlessly with WD NAS solutions, WD Red hard drives are qualified to work with a wide array of WD OEM partners. A regularly updated list of WD Red-qualified products and manufacturers is available on the WD website at http://www.wdc.com/en/products/products.aspx?id=810.
