can an ssd fit in any laptop?

not yet i dont know how to either and what storage quantity should i need because i had a macbook once and was fine with 125gb but it almost got too close to the point where it was done
 


What size drive is in there now?
How much used space?

You probably could get away with a 500GB SSD.
Samsung 750 EVO, for instance. $135
