This is what I do.
Only have your SSD fitted in the correct Intel port that you wish to use.
BIOS to default. F5 and enter.
Set SATA mode to RAID
F10 to save and enter.
Use your USB OS install drive and install OS.
Then once done add the two hard drives and set them up in the RAID configuration application. Ctl I during the post process.
Download the Microsoft USB Tool and ensure you use a OS that is SP1 - this I find help big time.
