Abbreviation of
Enhanced Small Device Interface, an
interface standard developed by a consortium of the leading
personal computer manufacturers for connecting
disk drives to
PCs. ESDI is two to three times faster than the older
ST-506 standard. To use an ESDI drive, your
computer must have an ESDI
controller.
Introduced in the early 80s, ESDI is already obsolete. Instead, modern computers use a SCSI, IDE, or EIDE interface.
