By comparing these two types of information, the control unit to which the hard drive belongs is determined. If the hard drive belongs to the IOH controller, it indicates that its interface is an IOH SATA type directly associated with the IOH. If it does not belong to the IOH controller, it can be excluded as an IOH SATA hard drive, pointing to an M.2 SATA interface type.
