EIDE : Computer Hardware Buyers’ Glossary

I have left this tombstone entry for historical interest.

EIDE (Extended Integrated Drive Electronics) It is now usually called PATA (Parallel ATA) It was the most common method for attaching hard disks and CD-ROM (Compact Disc — Read Only Memory)s to the computer, but has been replaced by SATA (Serial ATA). The alternative is SCSI (Small Computer System Interface) SCSI is more expensive, but is no faster if you use Windows-95. SCSI is faster if you use OS2, NT, W2K, XP, W2003, Vista, W2008, W7-32, W7-64, W8-32, W8-64, W2012, W10-32 and W10-64. EIDE uses ribbon cables with 40 conductors. You can’t connect a SCSI drive to an EIDE controller or vice versa. Most modern PCs (Personal Computers) have two EIDE adapters. Each one can handle two devices, one designated as the master and the other the slave. You must configure jumpers on the devices to select standalone master, master with slave or slave. There are problems with some EIDE controllers. Controllers and devices are speed rated: ATA (Advanced Technology Attachment) 100 = 100 megabytes per second transfer rate, ATA 66 = 66 MB/sec, ULTRASYNC 33 = 33 MB/sec. The higher the number, the better.
