Seagate GoFlex Desk 4TB USB 3.0 Hard Drive Review @ Bigbruin.com
 

The massive capacity of the Seagate GoFlex Desk 4TB USB 3.0 hard drive could probably store your entire media collection with room to spare - and with the USB 3.0 interface it can transfer it with lightening speed. The included software is more of a basic solution; if you want something a bit more robust you'll have to pony up $50 or find another third-party solution.
