With a 256GB SSD ( or even a 120GB model ) you have room to install Windows and all your programs and games on the SSD. This will allow the SSD to do what an SSD does best and really increase your overall system responsiveness. You will never go back to a mechanical drive. The Samsung 830 is an excellent choice by the way.
Unplug any drives other than the SSD and install Windows. Then you can plug in any mechanical drives you have.
Use the mechanical drive for storage. Documents, pictures, music, videos....basically anything that you need copies of but will not benefit from being on the SSD. Personally I have hundreds of gigabytes of stored info and have 4 mechanical drives in my case in addition to my SSD. I also have 2 external drives. Some stuff that could never be replaced like pictures are also burned to DVDs and stored at a relative's house just so something like a fire could not destroy everything. That is a bit much probably but I have learned over the years that hard drives die just when you really need them not to!
