 From a software point of view, ATA made sense.  It succeeded ESDI, which,
 in turn succeeded the ST-412 interface.  In fact, from a software
 viewpoint, it's difficult to distinguish a PC ESDI drive from a 16-bit ATA
 drive.  So, there was a software protocol that was somewhat smarter than
 ST-412 already around, so it made sense to move that to ATA/IDE.
 ESDI drives were about as fast as SCSI drives of the time--and about as
 expensive.
 Not that I loved ATA/IDE--early drives could be very fussy about what
 other vendor's drives they shared the bus with.
