Dell E7240 second SSD possible?

Does the dell latitude e7240 support multiple SSDs? Ive been wanting to upgrade my dell latitude e7240 ssd but realized that a second ssd was a better option. first the e7240 has multiple mSATA slotswhich one is used for an optional wifi card, but can it be used for ssd with the obsolete mSATA port or will it fry the hardware or something?
