I use google drive 15GB free. I keep important stuff like wow interface settings (If I lost that I would prolly quit wow, I have like 100-150 addons) or other game files there. Also some documents and stuff. I think it works fine now a days. So yeah I dont have much to save. I dont download movies, music or anything, I find it to be pointless when I can stream everything *insert a black and white flag*
