   Low Voltage Differential
   LVD
      <hardware> (LVD) A method of driving SCSI cables that will
      be formalised in the SCSI-3 specifications.  LVD uses less
      power than the current differential drive (HVD), is less
      expensive and will allow the higher speeds of Ultra-2 SCSI.
      LVD requires 3.3 Volts DC instead of 5 Volts DC for HVD.
