|(storage, hardware)||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.
