I just got a 2011 iMac with the SSD and 2TB drive option. I know that the OS and Apps should run from the SSD, but what I'm curious is what to move to the 2TB drive and how best to do it. I imagine the user information mostly belongs on the 2TB drive as thats where the bulk of data will be stored. Do people move their entire user directory or create mount points and move things like "Downloads" and "Documents"? Curious about best practices. What I don't want is confusion not knowing which user directory things are at, and apps that need to save data to default user directories throwing things where I don't want them if I forget to change them. I've seen a lot of posts and blogs about just moving your whole users drive. Then I've seen others that use symbolic links so you can keep the speed of the SSD for some apps such as iTunes or MIcrosoft User Data (Office 2011). This seems wise, but messy.
