Quote from the review: "Barriers are meant to be broken. As capacities have increased and prices fallen, each company wants those bragging rights of having the "biggest," or at least the fastest.
We put three 1TB hard drives through the paces - Hitachi's Deskstar 7K1000 and Seagate's Barracuda 7200.11 (ST3100340AS) as well as their Barracuda ES.2 (ST31000340NS). Which one will come out on top?"
