4k PLEX Remote NAS Suggestion

[Enquiries]

I'd like to remotely (over the internet) access 4k movies/shows with Dolby Atmos audio data on my PLEX server. I will have 2 simultaneous streams at most (usually just 1). The PLEX client will be an NVIDIA Shield Pro so I should probably be fine with most NAS devices, but I'd like to get something robust enough to handle transcoding as though I didnt have the Shield Pro.

Thank you kindly!
