I just ordered 2 new Samsung 500 GB 870 EVO drives as my drives are getting older and now one is totally acting up. Before I do the swap I need to back everything up..but..  My computer is set up with the 2 SSD drives both 250GB EVO's. One is OS and the other is all my working DATA, mostly Cakewalk and Movie Maker files. I have a 3rd 1 TB drive as backup which I often copy folders from the working Data drive over to. I will also use an External drive so I'm pretty safe for back ups.
