If you're asking how to use the two SSDs in RAID 0 for Windows, you're going to have to reinstall Windows and install the RAID drivers before the setup. But someone else will have to fill in how to do that because I never did it.
Since he's saying the Baracuda doesn't show up... we can guestimate that he's already past Windows installation...
OP, you'll need to be logged in with an administrator account, Right click "Computer" in the start menu (or "My Computer" if you put it on your desktop) & select "Manage". Then click on "Disk Management" under the "Storage" section. Your computer will automatically search for all connected storage devices & should find the Baracuda & a window should pop up asking you what you want to do with the new drive. Just initiallize it, format it & you should be good to go.
