If you have the need for a high performance drive, and are willing to drop $900 on 2TB, then the My Book VelociRaptor Duo is a great choice. In our tests, this drive more than exceeded our expectations, posting faster transfer speeds than most drives we've seen. Its myriad of other features made it incredibly easy to set up and use, and with two 10,000-rpm drive mechanisms and two Thunderbolt ports, this drive is the stuff media professionals dreams are made of.
