    They are assumed to have the same capacity.

    ReadyBoost is an "aid" to Superfetch the page-filing utility.
    It's effectiveness depends mainly upon two things -1. the type HD - if the
    Windows Experince index for the HD is "5" or higher ReadyBoost does not
    increase performance - if index lower, as usually for laptops, Readyboost
    helps 2. ReadyBoost increases performance when non-sequential read/writes
    are involved - HD more effective for sequential stuff.

    Also a ReadyBoost cache is included by Superfetch whether or not an external
    memory device is attached.

    Data sent to readyboost cannot be accessed normally (explorer, etc.) - the
    data is encrypted and are copies of data stored by Superfetch which is why
    the device can be removed without loss of data.

    Another function of ReadyBoost is to monitor data access over time and
    improve Vista starup time.
