I have the Asus P6X58D Premium motherboard. I recently upgraded from a HDD to SSD so thought I would make use of the Marvell 6Gb SATA port but I noticed when I ran the benchmark in Samsung magician I'm getting much slower read/write speeds than advertised (Read 374 mb/s write is 250 mb/s).
When I first plugged the drive in I used one of the spare SATA 3Gb ports and the benchmark told me as it was plugged into a SATA 3 port I was not getting optimum performance. So I plugged it into the dedicated 6Gb port and it hasn't given the results I was expecting.
The motherboard has 6 x SATA 3Gb ports and 2 x Marvell 6Gb ports.
