Speed matching

To improve system performance, the drive uses a technique called speed matching to
dynamically adjust its native (uncompressed) data rate to the slower data rate of a
server. With speed matching, the drive operates at one of six speeds when it reads
or writes the Ultrium 3 or Ultrium 4 cartridge format. Native data rates are as
follows:
v Ultrium 4 (read/write): 30, 48, 66, 84, 103, or 120 MB per second (MBps)
v Ultrium 3 (read/write): 30, 40, 50, 60, 70, or 80 MBps
