You do not want your expanded storage as a disk cache (you rather had main memory if it were for that). I believe MDC in main memory *is* useful, but the defaults make it often too agressive (I like to set the ratio much lower than 1, but others prefer to set a max). This is different when main memory is less than 2G because that does not have the 2G issue and is very small to allow for some MDC benefits.
