BOSTON - (Photoshop World Booth No. 615) - Mar. 25, 2009 - WD® (NYSE: WDC), the world's leader in external storage solutions, today expanded its My Book® family of external hard drives to include a 2 TB capacity, the largest available capacity in a single-drive system.

The new 2 TB My Book family includes: My Book Studio Edition™, My Book Mac Edition, My Book Home Edition™ and My Book Essential Edition™ models.

Market research shows that consumer creation and acquisition of digital media is growing rapidly, driving demand for increasing storage capacities. According to market research firm IDC, the number of digital cameras and camera phones in the world surpassed 1 billion (Mar. 2008). Separately, market research firm GfK reports that HD (high definition) video camcorders are experiencing record growth and now account for 42 percent of total camcorder sales (Aug. 2008). HD video requires massive amounts of drive space: at least 8 GB per hour of video. Since 2006, when Apple® began offering movie downloads, the Apple store has already sold more than 250 million TV episodes and sold or rented more than 33 million movies (Apple, Mar. 2009).

"The popularity among consumers of high-definition video cameras, digital photography and digital music downloads means that users are filling up their computers with massive amounts of digital content as fast as they can click 'save.' As the volume and value of users digital content grows, backing up data on multiple CDs or DVDs becomes time consuming and inconvenient.
