The Seagate 1TB drive swept all the other drives in the HD tune benchmark and took two out of four in the Sandra benchmark, which gives an overall total of about 80% in the win column. The 1 TB Barracuda is a second generation perpendicular recording drive, hence the 7200.11 as opposed to the 7200.10 that the 750GB Barracuda, so this could possibly be the reason why it does a little better than its little brother. Or could it be that my 750GB drive is starting to wear down a little considering the punishment I've put it through.
