Hard drive storage company Western Digital was in attendance at Macworld | iWorld 2012 last week showing off its MyBook Thunderbolt Duo setup. The unit is a two-drive box that can hook up to your Mac through the Thunderbolt port, and it's Western Digital's first entry into the protocol. As you might imagine, using Thunderbolt means the transfers are much faster. Western Digital's rep said that while a transfer of 6 terabytes (the drive will likely debut in 4 or 6 TB models) would normally take up to 6 days to completely write over, the Thunderbolt drives can do it in six hours. That's big news for backup fans, who are very much awaiting WD's new models. The drive we saw was only a prototype model, and official pricing or release information hasn't yet been announced, unfortunately.
