Pros of loading CS6 on your SSD v HDD
Put everything you can on the SSD. Applications you use a lot (Say PS) are a no brainer to go on the SSD.
Use the HDD for stuff that won't fit on your SSD.
If you want to speed up as much as possible keep your working files on the SSD and move them onto the HDD when you are archiving them. Such a thing is simplicity itself with tools such as Lightroom.
