OK - I can move the swap file to one of the 500GB disks I use mostly as a scratch disk, which would be ideal. Keeping it on the SSD would probably kill it quickly with all those writes. But as far as the apps go, I would think most should remain on the SSD so that they load quickly and react quickly. That's mostly reading going on which is supposedly much faster than using mechanical drives. As it stands right now, I could probably get everything in below 40GB so I'm guessing that I wouldn't need to use that app very much to change much of the structure, just move my "mydocuments" folder and the rest. Not sure whether I want to keep Outlook pst files on the mechanical since the speed differential could be huge and I use those regularly, but you guys might know better than myself about whether that's still better kept on the mechanical. Thanks for the input.
