Thinking of Upgrading Storage

Hey everyone! I built my PC a few months ago and at the time only bought 1 TB SSD storage (wd black sn850x), but I've realized a lot of games take quite a bit of storage, so was planning on upgrading it this upcoming Prime Day. Thinking of buying an extra 2 TB m.2 SSD from Amazon, and just wanted some advice on what you guys would recommend! The main purpose is just extra storage for games honestly.

My MOBO is the ASUS TUF GAMING B650M-E WIFI which I am fairly sure can support 2 m.2 SSDs but pls correct me if I'm wrong!

Thanks :)
