How many times faster is accessing RAM $($which is itself slower than cache$)$ than accessing $($reads and writes$)$ data on a SSD$?$ i$.$e$.$ How many clock cycles pass during the time it takes to perform one SSD access? Use a clock speed of $3$GHz$.$ For SSD speed, use an average of $3$ms$.$ Reads are faster, but writing is a two$-$step process, so $3$ms is a reasonable average.
