I will be purchasing an SSD in the VERY near future and wanted to run it in AHCI mode but would also like to run 2 2TB HDD's in Raid 1 (for data integrity). Is that possible on this board? Would I need a separate raid controller for the 2 HDD's? When I select AHCI in Bios all Raid options go away and visa versa.

With that question in mind, all documentation state it is advised to use the Intel Sata controller for boot devices but if I use the Marvel for my boot SSD then I will be able to use the Intel for my Raid 1. How bad of a performance hit will the system take using the Marvel controller for boot SSD?
