My Crucial M4 256 gig SSD is on its way. I want to do a clean install of Mountain Lion to see if that gets rid of some chronic, intermittent bugs (screen saver doesn't activate some times; other times machine will not wake up from sleep) and general sluggishness, excessive beachballishness. My question is this: What's the best way to do a clean install on the SSD, then incorporate the SSD with my 2 terabyte HD? My user folder is 380 gigs, so I'll definitely need applications/system on one disc and user folder on another. So what's the best way to do that with a clean install? Should I create users that mirror existing user names, then link them somehow (I've seen "symlink" or something referenced, but don't know how to do that.) Any advice on the best approach?
