I have just purchased a 120GB SSD with the intent of making it my boot drive. I'd like to keep it as lean as possible since, y'know, it's so small (Heaven help me). I've read Can I move my home folder in Mac OS X? and Moving Mac OS X user folders? which discourage moving the entire home dir to a data drive. Is it possible and less-dangerous to leave the home directory on the boot drive but move the big data directories to a slower drive and symlink to them?
I have the same thoughts with the /Applications directory, but maybe I should make that a separate question?
