Smartdrive
     
         A {Microsoft} {MS DOS} {disk cache} program
        to speed up disk access.
     
        For most users, a 1MB cache is sufficient.  Devoting more
        memory to the cache offers diminishing returns, since the
        additional cache hits become fewer (and the extra memory could
        be better used to reduce {swapping}).
     
        Typing SMARTDRV /S at a DOS prompt shows the cache size, a
        hit-and-miss report, and information about which drives are
        being cached.  The hit-and-miss statistics are crucial for
        gauging the effectiveness of SmartDrive settings.  A score in
        the high 80s shows that SmartDrive is well configured.  Run
        SMARTDRV /S several times during a Windows session and note
        the-hit-and-miss figures each time.  If your percentage
        usually falls below 80 percent, you should consider increasing
        the cache size.  You can edit the SMARTDRV line in your
        {AUTOEXEC.BAT} file to increase both the InitCacheSize and the
        WinCacheSize parameters.
     
        SmartDrive Monitor is an undocumented Windows program that
        comes with DOS 6.0 for logging and controling the cache.
