Currently, my network storage is just an external HDD (5400 rpm) connected to my router (TP-Link Archer C2 AC750) via USB. I'm using this network storage for storing large files, watching movies (by directly playing the file), and watching movies on my smart tv using plex (using my PC as the plex server). The reason that I'm looking for a NAS is that there are times, when many users are accessing the storage network, wherein the transfer speed is so slow (10Mbps) and the movies that I'm watching lags.
I'm not sure if it's a good idea to transfer the plex server to a NAS or just keep using my PC as the server. All of my movies' codecs are compatible with my smart tv so I'm just using "Direct Play" in plex and I think I don't need any transcoding. If I'm using the NAS as the plex server, plex and transcoding does not support all NAS available. So my first question: Is it wise to buy plex compatible NAS or just keep using my PC as my server? My next question (based on what will be the answer to my first) is What NAS should I get that is budget-friendly? Lastly, What HDD should I use on my NAS?
Thanks for your help guys.
