After all the tests were done, the Seagate Barracuda 7200.11 ST31000340AS 1TB internal HDD ran neck in neck with the Hitachi Deskstar 1TB drive. The Seagate drive ran away from the Hitachi in the HD Tach tests and the Hitachi pulled slightly ahead in Sandra benchmarks. The Seagate Barracuda 7200.11 ST31000340AS 1TB internal HDD is a speedy drive with lots of storage space that is perfect for heavy media users.
Pros: Fast speeds, Huge storage capacity, Faster than a Raptor HDD
Summary: This difference in areal density proves to be a fatal flaw for Hitachi’s drive, and the Caviar GP’s speeds are constrained by its focus on energy savings. The result? Seagate’s 7200.11 terabyte drive is the fastest we’ve yet tested in the Lab, hands down. It doesn’t come with any additional features—no encryption, no power-savings, no backup—just speed. Although we’d welcome the others, speed is our primary concern.
Pros: You’re staring at the fastest terabyte drive on the market.
Cons: The Barracuda’s burst speeds aren’t quite on par with Western Digital’s. That’s a minor detail, but a detail nonetheless.
Excerpt: By combining proven components and state-of-the-art technology, the Seagate Barracuda 7200.11 family delivers up to 1 TB of storage. Designed with Seagate's 2nd generation perpendicular recording, the capacity, reliability and performance of this drive ensure the longevity of digital content for years to come.
