Western Digital announced today that its My DVR Expander™ is now available with 1 TB capacity. TiVo Verified™ compatible with TiVo Series3™ and TiVo HD DVRs, the new My DVR Expander is capable of storing up to 140 hours of high-definition (HD) television programming based on 1 TB of hard drive storage.

The ability to expand DVR storage with an attached external drive was something that we explored in both domestic and international consumer studies last year - TV 2.0: The Consumer Perspective and Entertainment 2.0 in Europe. We found fairly high demand for this kind of solution, particularly among consumers in the U.S., the U.K., France, and Italy.
