NAS Advice - Enquiries - 02-22-2023
I actually already have a TS-453D. In it, I have two 6TB HDDs and two 12TB HDDs - setup in RAID between the two pairs. I have two 860 EVO SSDs installed for the QTS OS. I thought this would be a powerful enough NAS, but it struggles to play a single 720 video (h264 mkv with AC3 audio) if I tell it to play VOBSUB subtitles. It's playing directly through ethernet to my Samsung Q8FN TV, so I can't figure out why it struggles so much. Turning off the subtitles helps, so my best guess is that it just struggles to burn them in, but I would've thought it wasn't that bad. Is there anything I can do? I could go through my libraries, and try to pull out all of the PGS subtitles and make SRT versions, which seem to work fine. OpenSubtitles isn't reliable and never matches up.

Yes, you are correct that subtitles can cause transcoding, which can put additional strain on your NAS, especially if the subtitles need to be burned in. If switching to a different subtitle format, such as SRT, helps with the playback performance, then that could be a good solution.
In terms of hardware, your QNAP TS-453D should be powerful enough to handle most media playback tasks, including playing 720p videos with subtitles. However, if you are experiencing performance issues, there are a few things you can try:
Make sure your QNAP NAS and Samsung TV are both using the latest firmware and software updates.
Check your network connection to ensure that it is stable and fast enough to support streaming high-quality video.
Check your video transcoding settings to make sure they are optimized for your hardware. You may want to experiment with different settings to see which ones work best for your specific configuration.
Consider upgrading your NAS hardware, such as adding more RAM or upgrading to a faster processor, to improve its performance.
Use a media player app, such as VLC, on your Samsung TV that supports subtitle playback without transcoding. This can help reduce the strain on your NAS and improve playback performance.
