What you certainly mean are the sub-folders within the “ASMedia 106x SATA3 AHCI&RAID Drivers & Installer Sets”. Nevertheless the OS will take and install just 1 driver (.sys file), depending on the OS and the HardwareIDs of the on-board ASMedia SATA Controller.
Please keep in mind, that the SATA Controllers can run in different modes (IDE/AHCI/RAID). All of them are managed by 1 driver (.sys file), but with different install configurations (determined by the related .inf file).
It seems, that the ASMedia SATA3 drivers v3.3.5.0 do only support Win8-10 in “AHCI” mode (subfolder “stahci”), whereas the older drivers additionally do support the “RAID” mode (subfolder “stor”). The “scsi” subfolder of the much older drivers have been designed for Server mainboards running W2k3 (that is why they contain a TXTSETUP.OEM file). If you want to know more details, please contact the ASMedia Support.
Don’t be afraid about an interaction of different storage drivers. The Disk Management of all Windows Operating Systems prevents, that a certain Storage Controller uses different storage drivers simultaneously resp. that different storage drivers interfere each other.
