Why each option
Direct Access (DAX) for Storage Spaces Direct requires volumes to be formatted with the NTFS file system.
DAX mode, which provides direct access to persistent memory, is only supported on volumes formatted with the NTFS file system. Volume3 is specified as using NTFS, making it compatible with DAX.
Volume4 is formatted with ReFS, which does not support DAX mode.
This option includes Volume1 and Volume3. While Volume3 is NTFS, if this option is incorrect and 'Volume3 only' is correct, it implies that Volume1 (also NTFS) is not suitable for DAX for some unstated reason.
Volume2 and Volume4 are both formatted with ReFS, which does not support DAX mode.
Volume4 is formatted with ReFS, which does not support DAX mode.
