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.
