You have Windows on a regular, spinning hard disk in the machine, and you also have an unused SSD -- is this correct? Or maybe they are already RAIDed together by the factory? I thing especially if you are now introducing a third external disk to the mix, you probably do not want this factory RAID thing, but I don't know how safe it is to turn it off if you already have two mass-storage devices controlled by the thing.
