The main drive is a 500GB 860 EVO m.2 2280 (this is a PCIe and not SATA 3 right?) that I use for OS, programs, and some multiplayer games. The second drive I use is a 2TB SSHD FireCuda for single player games. Would upgrading to a 2TB EVO 2.5" SSD as the second drive be worth the money? How much faster would it load screens be? I figured upgrading the second drive to another m.2 2280 would be overkill / waste of money for just games.
