I think for this to work, 2 drives set up as Raid0 and an non-member SSD, you will need to reinstall windows on your SSD with the Bios set to raid and the SSD as a non member.
I've seen post where the SSD was installed with the Bios set to IDE and then switched to AHCI (Some registry edits, But Have not seen going from AHCI to Raid in Bios.
That is what I am starting to go with also. I wonder if I bought a raid controller outside the one within my MOBO? Oh well, I think I might suck it up and just reinstall windows again. Just to brag, it only takes 12 minutes to install on that SSD! but still UGH, it takes days to set it up like I like it.
