Seagate 2TB Barracuda SATA 3 6Gbps Review

Testing:

Crystal Disk Mark 2.2: Crystal Disk Mark is a hard drive benchmark designed to measure the read and write speeds for the drives in in 4k blocks, 512k blocks, and sequential data.

The 2TB Barracuda XT delivers better performance than the other disks in all categories, save the 4K write test where the 74GB Raptor is faster. The performance differential between the SATA 6 Gb/s and SATA 3 Gb/s is measurable on the 2TB drive.
