symbolic links
this is what i use in windows to manage them:

Look up a program called Steam Mover or Steam Tool.
Will move your 'Selected Game' directory to another drive and create an NTFS junction for them. Really handy and convenient.
A must for someone who has a large Steam collection and wants to move things onto an SSD (and back again) with ease.
Just be a bit careful with junction points and symbolic links, they're below the OS level so no apps can tell they're being redirected to different physical parts of the drive that can cause some issues when the target drives are removed, become inaccessible or if you try and use tools to error check or defrag for example.
By all means use them, just read up about them a bit first, I wouldn't recommend novices do this, if you're really low on space then grab a 2Tb-3Tb hard drive instead.
Same goes for RAID 0, that has increased failure risk and shouldn't be used by novices unless you know what you're doing.
Yeah, but it would take days to redownload everything.
I use SteamTools, but I also just uninstall games that I have either completed or know I won't be playing anytime soon. Oh, and I only have a 500GB HD.
