Seriously,

one name was forgotten, WD, that the drive maker but the chip maker. 
The chipset used for
board then drive level was the same or successors and the came from WD.

BTW if you scan two pages on in the cited PC Magazine u will find CompuAdd offering add-on “HDDs” for the “IBM-ATs” and “IBM-XTs”  from MiniScribe and Seagate - at that time Seagate did not have an ATA (or IDE) drive so maybe CompuAdd’s drives weren’t ATA as we now know it.
