Why a Mount vs Disk volume for local data storage in an MS Windows media agent appliance

Hello Team. I’ve come across Windows media agents with internal data storage in a raid 5/6 stripe (single logical disk in Windows) wherein instead of formatting the disk as a volume and assigning a drive letter to point the library in CV to a mount is created for CV to write the data to the disk. When I questioned the person who did this, his response was that long ago he read in CV docs this was a best practice to follow for security/ransomware prevention purposes; to make it harder for a bad actor who gained access to the server to read files on the volume. I myself vaguely recall this may have been a recommendation in the v8/v9 days. Does anyone have any knowledge of this configuration as a ‘best practice’, any docs ? Any comments as to the effectiveness ?
