AHCI stands for Advanced Host Controller Interface, which means that it has to do
with an interface that a controller presents to a host OS, not with an interface
between the controller and a drive.  OTOH, AHCI is applicable only to SATA
controllers.  The opposite is not true, though, not all SATA controllers are AHCI.
