Enhanced Small Disk Interface

(storage, hardware)(ESDI) An obsolete hard diskcontroller standard, first introduced by Maxtor in 1983,and intended to be the successor to the originalST-506/ST-412. ESDI was faster and more reliable, butstill could not compete with IDE and SCSI.

EDSI used two cables: a 20-pin data cable to each drive and asingle 34-pin control cable daisy chain with the controllerat one end and a terminator at the other. In PCs, itsupported up to two drives at 1-2MB/s with drives up to 2GB.
