Was looking at the tvs-h1288x. Looking for something my family of 5 can use with good remote use. Sometimes 2 or 3 members of the family will remote stream. Trying to find a good nas that can plex transcode up to 4 connections to be safe.
Yes, Qnap 88x series are their most powerful desktop NAS. There is no graphics chip on these models, but the CPU is so powerful that it can convert using software transcoding even 4K video files. Alternatively, you can look at i5 and i5 based models like TVS-1282 and TVS-872XT that do feature video chip.
Another option would be TS-873 with a dedicated PCIe graphics card. This way CPU is not that important and a card will do all the heavy work.
I hope this helps.
