SATA 6Gbps controllers compared

There are several SATA 6Gbps controllers on the market and Expreview has published a test in which it compares a couple of them, you can check it out over here.

The site concludes the native SATA 6Gbps port of Intel's P67 offers the best performance, closely followed by the native support of AMD's SB850. The third-party chip from Marvells offers less performance and the SATA 6Gbps bridge connection on the tested P55 delivers worse performance than SATA 3Gbps.

On the whole,SATA 6Gbps port through third-party chip bridge connection in P67 perform worse than that of native support,but it’s much quicker in reads than SATA 3Gbps,while inferior to SATA 3Gbps in writes.When two native SATA 6Gbps ports are consumed,we should think it over which port we should use,it’s suggested to use SATA 6Gbps port provided by Maverll chip with better read speed.
