You are booting off of and running applications on an SSD, but everything else is saved to a different internal HDD for storage? That is, the OS is on the SSD, but the desktop and whatnot is tied to the other HDD? Does that make sense? Basically I am wondering if it is possible to boot from a smallish SSD and not have to worry about writing to it and then having to transfer files later.
yes. all you have to move your Home folder or even the whole Users folder to the HDD. http://www.tuaw.com/2009/05/14/tuaw-tip-moving-your-home-folder-to-another-disk-or-moving-it/ http://www.ransom-note-typography.com/index.php/SSD_and_Your_Home_Directory
