Introduction to EIDE

EIDI is a primary interface that is used in the desktop computers to handle the communication between the hard drive and other mass storage devices’ interfaces and the CPU.  EIDE stands for Enhanced Intelligent Drive Electronics and it is an improved version of the IDE interfaces.  EIDE provides the faster access to the hard drive and the support for the additional devices like tape devices through the AT Attachment Packet Interface.

EIDE has been adopted by the ANSI as a standard for the communication between the storage devices and the central processing unit.  EIDE was developed by the Western Digital Corporation.  Modern computers have built-in EIDE.  Because of the low costs of the EIDE it has replaced the SCSI.  It is also referred as Fast ATA or Fast IDE.  It supports the data transfer rates from 4Mbps to 16Mbps.
