Thank you for your quick response and information.
To summarize, it appears that the Intel controller is the most stable and best option to connect the C300, and especially if Raid 0 is to be used. Single drives can hook up to the Marvell controller but the speed increase and stability issues are not worth the gain and risk. The Marvell 9128 controller is hardware limited and future upgrades in drivers and firmware are not coming in the near future. It appears that this problem exists for all the boards that first came out with SATA3 ports.
Hopefully Intel will come out with a 6GB controller soon. You have provided the simplest and most useful information.
