Normally with SSDs you want the programs like games and applications you use and want to be speedier, so programs like photoshop and such should be on there. Their whole purpose is for speed so using it for storage really defeats their purpose. Some will say that you shouldn't install games that update frequently but current SSDs have life spans of 5+ years which is equivilant to HDDs so I would say any program you want to be speedier. Personally I have two SSDs, one for windows, OS and drivers and the other that has ALL my applications running on it. Storage is handled by a HDD.
