I have a 2tb drive USB3.0 I use for backups. I usually only have 1 to 2 games installed on my 480gb SSDs at a time. Right now I'm replaying Arkham Asylum then Arkham City. I have Saint's Row 3 and Skyrim installed waiting for their DLCs. I also have Gemini Rue and I'm downloading the FEAR series to backup and play later.
