Western Digital will demonstrate the fast data transfer rates of its upcoming My Book Thunderbolt Duo dual-drive storage system at the Macworld/iWorld show.

Thunderbolt technology will improve workflow speed and efficiencies for enthusiasts and professionals dealing with large digital files such as video, audio and still photos. The technology is capable of producing up to 10 gigabits per second of throughput on each of two channels in both directions. To put Thunderbolt's speed into perspective, HD media creators will be able to transfer a standard size full-length HD movie in less than 30 seconds.
