SATA2 has nothing to do with hardware RAID.
is going to be faster that software raid and why?
Beeing a consumer type board (AM2), the "raid on the motherboard" is in 99.999% of the cases just software raid implemented in their Windows drivers, a bootup setup screen plus some BIOS magic to get the OS booting.
And, yeah, they're all software RAID. Also, there isn't much to be gained from making RAID0/1 hardware. The software overhead isn't that big. For RAID5, having XOR done in hardware helps.
