no my friend. the motherboard DOES include a RAID controller. it has 2 actually. an intel and a marvell which is 6GB/s. it is connected on the intel controller. The reason I had to configure it in Windows was because it picked it up and then I converted it into GPT then created a stripe volume. (even though I had set it up using the Intel matrix utility onboard.
I did notice that eventually it was transferring at around 250MB/s between itself when copying and pasting a large set of files in different locations.
