No released NM10 based motherboard ever offered 6 sata ports that work in Linux. No NM10 based motherboard ever offered 4 PCIe lanes in a single slot. http://www.linuxtech.net/features/intel_atom_pineview_motherboards_overview.html. While you should be able to do either one or the other, NM10 will not support the combination and neither has ever been offered. Cedar Trail is all NM10 based and anyone who wants to do software RAID 6 will likely jump on the Brazos platform with its 6 sata ports and 4 PCIe lanes in a x16 slot. Where is Xeon Atom?
