You can carve up your storage any way you would like. If you have not started building and installing it's much easier. Let's say for instance you are installing windows and 5 other programs. When you do an install of any program you are prompted for a install directory. Just decide where you want the programs and install at will. I use my SSD for the OS-windows, and other programs that benefit from the speed, such as Adobe creative suite (graphics). This allows for future patches and programs to be installed on the SSD without using up all available free space. Other programs go on one of my hard drives, such as MS Office, games, TurboCAD, itunes.
