I have one SSD which I use as a data drive between both Linux and Windows. I used to run Steam games from it, but there were some small problems sometimes, so nowadays I just use it as a storage.
Generally it works just fine, but sometimes Windows does something weird with it especially when running updates, so that Linux can’t mount it. During those times I just have to boot to Windows desktop and then come back to Linux and it usually mounts again. If you totally get rid of Windows, I don’t think this will happen to you though.
The older I get, the less I want to learn new competitive games because I just don’t have time anymore. It’s just nice to go back to something familiar every now and then.
