Demo of SATA600 (6gbs) by AMD and Seagate shows peak of 589mb/s

Despite its fatter pipe, SATA 6Gbps will use the same connectors as the existing Serial ATA standard. The spec includes new goodness beyond a higher throughput peak, too, but AMD and Seagate are only talking data rates for now.

While today's technology demonstration is not a product launch, we can tell you that the demo drive is based on Seagate's current Barracuda 7200.12. It's running on a next-gen AMD chipset with a brand new storage controller of the company's own design. That setup, according to Seagate, has hit a peak data rate of 589.09MB/s.
