The actual peak SCSI bus transfer rate of the drive is 4.8 MB/s, but
this is only the SCSI bus rate, not the drive rate.  The raw drive
rate is 3.0 MB/s, but that does not account for intersector gaps,
head switches, or single cylinder seeks.  In actuality, the maximum
sustained transfer rate off the media is about 2.1 to 2.2 MB/s for
this drive (million byte MB).
