Setting up Hard Drives on SATA Ports - Config Options

I have an Asus P8P67 LE mobo that offers two Intel 6Gb/s SATA connectors and one Marvel 6Gb/s connector, as well as four 3Gb/s connectors.
I have four drives, two SSDs and two HDDs: a Samsung 840 Evo (250), a Corsair ForceGT (120), a WD SATA III (1TB), and a Seagate Barracuda SATA II (500GB).
My intent is to install Win7 on the Samsung SSD and Linux on the Corsair SSD. The HDDs will be data drives. So, the old Seagate HDD is easy - that goes onto one of the four SATA II connectors. The Samsung SSD goes onto one of the Intel SATA III connectors and the Corsair SSD onto the other Intel SATA III.
My question is: should I install the WD SATA III drive on the Marvell 6Gb/s connector or on one of the SATA II connectors? I have heard so many bad things about the Marvell SATA port.
In general, are there any apparent hitches to this intended setup?

You can connect any HDD to a SATA 2 (3Gb/s) port or a SATA 3 (6Gb/s) port and you will get the exact same performance. No HDD can spin fast enough to saturate a 3Gb/s port, let alone a 6Gb/s port. So connect your HDDs wherever you like.

The Marvell 6Gb/s controller was developed around the same time as 1st generation SSDs, so they can't handle the speeds of current generation SSDs. If you connect a current generation SSD to a Marvell 6Gb/s port it will get 6Gb/s speeds, but not maximum advertised speeds.

SSD's to the intel sata3's. HDD's anywhere you want. Optical drives I would leave on one the highest numbered intel sata2.

Thanks for the inputs. I believe I will try the SATA III HDD on the Marvel SATA III port, though realize it will not be hitting that transfer rate.
