Low Voltage Differential
LVD

    (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.
