Since Windows 10 is out I am gonna upgrade to it but before I do that I wanna get a SSD because right now I just have a Western Digital Back. I have deiced on getting the SAMSUNG 850 EVO 120GB and installing Windows on to it then upgrading it to 10. But before I get the drive will it work with Windows 10 ok? And another question what should I do with the Western Digital's windows installed on it should I delete it or keep it on or will I have to reformat the drive?
