Western Digital has gone on sale with the My Book 3.0 external drive that houses the next-gen USB 3.0 support. Announced earlier this month at CES 2010, WD MyBook 3.0 is one of the first USB 3 storage devices (the other one we heard was the Segate Blackarmour). USB 3.0 gives you 10x more speed than the current USB 2.0; however the sad part is that we are yet to see compatible systems hit our desks. For the moment you would only be able to use this HDD in USB 2.0 mode on your current system (thankfully USB 3 is backward compatible) or install a USB 3.0 compatibility card.
The 1TB MyBook 3.0 goes on sale in India at Rs 9990 (Intl price $179) or Rs 11990 with a USB 3.0 adapter card (Intl. price $199). The 2TB version would hit the markets by month end.
