pretty much what the title says atm im looking at a 500gb Samsung 960 evo or a 1tb Samsung 960 evo. I plan on putting my os and probably the 2 or 3 games I play the most if I have room maybe all my games and everything else i.e. movies, files, docs etc.. on my 4tb HDD and maybe get a sata SSD later on down the road for an in between drive for stuff I don't wanna use space on m.2 for but I want to run faster then the HDD can like maybe some other games that I don't play much
