BTW the OS is already installed in the ssd.
Will I need to do a fresh re-install of the OS?
The reason I'm doing this is to give my 3tb hdd a boost so I could install other games and applications there and still have fast startups. Since I think my ssd would eventually ran out because of the humongous sizes of games nowadays.
I know it wouldn't be ssd fast but at least it's not regular hdd slow.
