I have 2x Seagate 2TB 7200 RPM drives and 2x WD Green 1TB 7200 RPM drives. I'd like to do RAID 10 with the 2TBs as the striped disks and the 1TBs as the parity disks. I am using an MSI Z87-GD65 board. Is this possible?

You can create a 4 x 1TB RAID 10 (2TB usable). All pieces of the RAID need to be the same size. You would have to exclude 1TB from each of the 2TB devices. It can be done, (not sure if it can be done with just your MB) but it isn't the optimal solution. You might also be able to create two RAID 1 volumes and then concatenate them in Windows to create a 3TB volume. Any time you make a storage implementation more complicated, it increases the risk of something going wrong and loosing all your data.

You would probably do better to create a RAID 0 with the 2 1TB disks, then do FREQUENT backups to the two 2TB disks. Then if something bad happens you have two chances of getting your data back....
