Seagate Constellation 2TB Hard Drive

The other day we took a look at Western Digital's 2TB offering, it's only fair that we see what Seagate has to offer as well. Seagate offers both the Barracuda XT and Constellation drives in 2TB capacities. Today we will  be taking a look at the Constellation. In the past we have reviewed a 2 1/2 inch Constellation drive, I'm curious what four times the capacity and a larger form factor has done to its performance.
