Netdrive 3 local drive option

Hi I need help understanding the local drive option in Netdrive 3.

I have been using Netdrive 3 to mount my GSuite drive for my plex media as a networki mount, however what are the implications of using the local drive option instead, I have set it up but was wondering how this will affect disk space on the local machine.

Also does anyone use this solution as a way of sharing the drive to another machine (I was thinking of using the shared drive as the media source for a Nvidia Shield Plex Server).

Would this cause Google API bans.

Any help would be great.
