Playing Sims 4 with mods on external hard drive 2026

Hi! I have never been on a forum before so I apologize for all the things I do wrong. I want to find out how the best way to play Sims 4 through an external hard drive works. Everything I can find is still using origin and players are saying it’s different. Can someone please tell me the correct hard drive to buy and how to actually do it? Thank you!
