WyomingKnott :
Little-accepted truth: if you are using software that has massive temp-file activity, such as Adobe software, the SSD is the best place to put the scratch space.
QFT.
Too many people strive to put that scratch space on a HDD, in an effort to limit write cycles on the SSD.
BAH! That's what the SSD is there for...speed Use it!
I have a seperate 120GB SSD for exactly that. Cache space for Lightroom, video applications, 3D CAD application, etc, etc.
