The need to clone only OS to SSD

I recently bought a new SSD drive and want it to be my Windows 7 system drive where i just save all my Windows installation and some programs & games, so that my boot speed and app running speed are faster. The SSD is 120 GB and the system partition is 150GB, but only 50GB are used, so there is plenty of space. I don't know if it's safe to clone this partitions to SSD, or if it's possible to clone only OS partition but not whole HDD?

Answer: Cloning is the easiest way to migrate OS to SSD including the operating system, system customized settings, personal files and installed programs on the system drive, thus you don't need to reinstall all of them. And a reliable disk cloning software can ensure your computer boot from the cloned SSD successfully.
