Data flow question

Currently I have everything running off local storage but I’m looking to change it to using my NAS since my local storage is almost maxed out. My question is related to this type of setup:

  • NAS for storage
  • Plex Media Server running on Mac
  • Multiple Clients

If a client is going to Transcode, I’m sure the data flow for that video is like this:
NAS —> Mac --> Client

If a client is going to Direct Stream, I’m guessing the data flow for that video is like this:
NAS --> Mac --> Client

Now if a client is going to Direct Play a file, is the data flow the same or will it go:
NAS --> Client

Thanks, that was what I thought but I was hoping they’d be able to pass the token or something similar.
