I never tried it before since I don't have SSD. I have a plan to buy SSD to use it as a primary/boot drive. 64GB should be enough. Since I have many software that I'd like to use, should I still be able to install softwares or games on secondary hard drive?
Steam, digitally distributed games from steam can all be on a secondary drive.
But, some retail games (Games from physical stores with discs) need to be installed
onto the C: drive.
I'm not saying that all of them do. In-fact you won't actually know until you install the game and try to run it.
But, most modern PC games do not have such limitations.
