The mobo has ONE Marvell port (grey) that is supposedly faster than the 4 black Intel ports (I think). I think the second Marvell port may be the little internal SATA slot. I moved the SSD to a black Intel port which says it supports 6 Gigabit in System Profile, but negotiated at 3. I moved the optical drive to Marvell. The Samsung 840 Pro SSD shows slower performance in BlackMagic than my 2 striped RAID spinners (also in the Intel). The SSD connected to Marvell under Lion showed 4 times the write speed I get under Mavericks. I also note that System Profile says that Intel supports AHCI 1.30 and Marvell supports AHCI 1.00.

===================
Somehow my negotiated speed for Intel is at 6 Gigabits
But looking at the Marvell spec, my gosh, Link speed can go up to 5GT/s ? I don't have any device that will come close to that so...........
Not sure what I did different then you on the SSD - Intel connection though.
