Enhanced Small Disk Interface
     
         (ESDI) An obsolete {hard disk}
        {controller} {standard}, first introduced by {Maxtor} in 1983,
        and intended to be the successor to the original
        {ST-506}/{ST-412}.  ESDI was faster and more reliable, but
        still could not compete with {IDE} and {SCSI}.
     
        EDSI used two cables: a 20-pin data cable to each drive and a
        single 34-pin control cable {daisy chain} with the controller
        at one end and a terminator at the other.  In PCs, it
        supported up to two drives at 1-2MB/s with drives up to 2GB.
