  average seek time
  
     <storage> The mean time it takes to move the head of a
     disk drive from one track to another, averaged over the
     source and destination cylinders.  Usually measured in
     milliseconds (ms).
  
     The average seek time gives a good measure of the speed of the
     drive in a multi-user environment where successive read/write
     request are largely uncorrelated.
  
     Ten ms is common for a hard disk and 200 ms for an
     eight-speed CD-ROM.
