100%.

I know this is a thread for someone new, but perhaps as a future fix: I grabbed a mini PC to do plex transcoding and all of Plex’s content is on a separate NAS with a 14TB RAID. I think the mini PC has 500GB by default

I just received a Beelink brand mini PC with an N100 intel CPU with QuickSync.

After setting up PleX and updating the drivers, I was able to hardware transcode the same 4K HDR movie to two separate devices simultaneously (with subtitles and HDR -> SDR tone mapping). Based on headroom it seemed like I might be able to do another. Others say it can do like up to 8 transcodes of varying source quality.
