So i currently have all my movies ripped to an external hard drive mainly in 1080p mp4 format and am currently using plex on my mac. I'm wanting to stream them from my hard drive to ATV 4, without my mac having to be switched on and looking to spend no more than £100 on the hardware setup. My two option are Buy a second hand 5th gen Airport Extreme and plug in the HD via USB and stream to MrMc/Nasify/InFuse - Would there be any issues with speed given that the USB is only 2.0? Buy the following NAS and insert my current hard drive and use as a plex server. I'm aware this is a low performance model, however seems to be the only one in my budget. Will it be able to stream my 1080p mp4 files smoothly? Any other reccomendations? Thanks in advance for any input.
