    And if you look at the ratio between the access time of ram
    which is in the low nanoseconds (1* 10 ^ -9) (data and address must be
    present for at least
    the rated number of ns to guarantee a sucessful read or write). and compare
    it to
    the seek + rotational delay of a discrete spindal which is in low
    milliseconds (1* 10 ^ -3) that puts you at
    a ratio of about 1000000.
