How can setup two mirror raid pairs, (2x2 drives), on a Z87 chipset?

[TigerZero]

I have a motherboard with the Intel Z87 chip set. I want to setup two RAID 1 drives. One mirrored pair for the OS and one mirrored pair as a data drive. I have two 1TB SSHD drives to be used as a mirrored "C:" drive and two 2TB standard hard drives to be used as a mirrored "D:" drive. When I enter the boot time Intel raid manager, I have no problem creating the first "C:" mirrored set. But when I go to create the second raid set it does not allow me to select the other two 2TB drives for the creation. Am I doing something wrong? Or is it you can only have one raid set? If it is the later, then what about creating a software raid for the "D:" drive through the OS?

Also a side question. Are there any known issues or concerns about using SSHD drives in a RAID mirror arrangement?

Make sure all the drives are on the right controller.
Make sure the drive isn't already allocated to another array, the raid info is stored on the drive,not in the controller.

I am aware of what you said. So I guess the real question is: Will the Z87 chipset support two raid 1 sets? Not 2 raid groups/partitions within a set of drives, but 2 pairs of drives, each set independent of the other. If it does, I will eventually figure it out. If it does not, then I should stop wasting my time trying.

Yes, I am running two sets of raid 1 on my Gigabyte Z87 board.
