So I am building up a fair amount of data now, and I am needing a solution as to how to store it all. At the moment, I have: SSD (M4 124GB)= OS and Programs WD Black 640GB = Games (Indie games and all of whatever I have installed from Steam) and Music WD Green 1TB = Videos And then I have a 2TB WD for back up. The issue being I am running out of room. Do I get some more higher density HD and replace the drives? I can't just buy some more drives and add them, the case I have wont allow it. Or perhaps build a file server and have it all on there? Or should I build a bigger backup hard drive cage? Thoughts and ideas?
