StorAHCI replaces MSAHCI
Clients – Windows 8 Servers – Windows Server 2012
StorAHCI, a Storport miniport, supports serial advanced technology attachment (SATA) advanced host controller interface (AHCI) controllers in Windows, and replaces MSAHCI, an ATAport miniport.
There should be no change in functionality or performance; this driver supports all the same devices that MSAHCI supports.
This change is transparent to the user.
Update any utilities and scripts that rely on ATAport bindings. Do not rely on the drive name. Instead use standard disk detection.
