So I am looking into buying the MSI GS65 Stealth which comes with 256gb in the model I want and I don’t want to pay another $300 to get the 512gb model. I need the extra storage for gaming because I plan on installing more the 256gb of games. Can I hook up a external SSD drive and download the games on there and play them off of the external drive. If so how would that be done. Secondly can I use the thunderbolt 3 port on the laptop to hook up the SSD because I heard it is much faster then USB 3.1. If so are all external SSD’s compatable with Thunderbolt 3. Thanks so much hope someone can help.
