I've been reading my fair share of posts and can't seem to find existing advice that works for me. Being a NAS/Server noob it might also be my lack of understanding.
To offer some context, I recently bought a LG 55C8 with the idea to be enjoy & stream 4k content using Plex Media Server. I currently own a Nvidia Shield Pro and I have to admit it's a strong disappointment. It does it job with 1080p content if you get passed the bugs, freezes, laggy android interface and if Plex doesn't crash as well. However, when it comes to 4k content, it's like playing russian roulette. One piece of content might work one day and the same content will make Plex and the whole Shield crash the next day. Very frustrating. FYI, I only use my Shield for Plex.
Overall I feel I'm better off building a dedicated and more stable config that would store and manage my media and can be controlled by my laptop through WiFi (storage mgmt, file transfer etc...). I mainly stream video content (file size between 2gb and 20gb) as well as high res lossless audio. FYI, I don't require to stream multiple files at the same time. Transcoding one 2160p or 1080p at the time.
NAS configs seem to be ideal when it comes to storage, I'm however doubtful for 4K transcoding without spending my money on a premium set.
Below my questions,
Can I find something below $500 ?
What brand do I need to look at?
A lot of NAS have dual or quad-core Intel Celeron processors. Is that good enough?
Do NAS with GPU exist?
If my NAS is used for storage, is it better to run PMS on it or through a 3rd party? Knowing that I will probably use the Plex App on AppleTV or LG WebOs to stream the content.
If my TV, Apple TV and NAS are all connected directly to a smart switch I suppose I will be able to use to full extend of an internal Gigabit speed?
Looking forward for getting help and advice on this.
