Yet another PC build upgrade ask

What’s best recommendation for both running deep learning and AR + VR (augmented reality and virtual reality) and VR with a Titan X? I need to upgrade my SSD (totally max’ing out on space at m with my Rift and it’s driving me nuts and want to have more than optimal space running Linux, plus games, applications, deep learning, and game engines). I’m debating on Samsung Evo m2 1TB or Samsung Evo 1TB SATA. Thoughts welcome.
