I recently purchased a new Samsung 850 pro 512gb ssd. I currently have a Samsung 840 Evo 120gb ssd with my Windows 10 operating system installed. I also have a 1tb hard drive with some files. I am looking to install Windows 10 on the new ssd. Should I delete/reformat my 120 gb ssd before installing the new one or will that be in the installer for windows. Please explain this procedure. Thanks -Peter
