Honestly you would be better just buying a new BIG SSD for Windows, then use the smaller one for the Hackintosh.
Buy running them in RAID you lose some things with SSD's like TRIM to keep the running fast. Also you don't get a lot of real world benifit from the RAID 0 of SSD's. Also if something happens to the RAID, or your BIOS is reset BAM! RAID is GONE.
Moving your exsiting windows over is easy. you can use the samsung software, or most of us on here, like to use Macrium Reflect. It is free.
