Seagate 2TB Barracuda SATA 3 6Gbps Review

Testing:

AS SSD v1.1.3466.29641: AS SSD is a benchmark designed for the speeds of solid state drives, however it will also work for traditional hard drives. It is designed to measure the read and write speeds and access time for set block sizes. It also assigns a score to the read, write and overall performance of the drive.

The only spots the 2TB drive from Seagate showed any weakness was in the 4K read and write testing and the read Access time testing, where the Raptor's higher spindle speed helps it out. In the rest of the testing, the 2TB drive is the top of the field and the difference between the SATA connections is not something you would notice.
