If the server's net (compressed) data rate is between two of the preceding native data rates, the drive

calculates the appropriate data rate at which to operate. Speed matching dramatically reduces backhitch,

the condition that occurs when a tape stops, reverses, and restarts motion. A backhitch is usually the

result of a mismatch between the data rates of the server and the drive.
