I know very little about NAS configurations, so I'll explain my basic workflow, and hopefully others can offer some reasoned suggestions. I have a desktop PC that I used as a central media server; it contained several HDDs for media storage, and I would stream those files to other devices on the network (Plex for the TV). I think I have about 2.5TB of video files, and about 500GB of music files (and counting). The PC is having issues and will crash/shutdown after a few hours. This means the media files are unavailable on the network, and so it's essentially useless as a media server. Enter NAS. What NAS solution would be best, given my workflow? The main computer is a MBP, and the router is an Apple Airport Extreme. The two HDDs that have most of my files are a 500GB (5000rpm) Seagate that's probably 10+ years old, and a 3TB Seagate (7200rpm) that's about 2 years old. I presume I would have to replace both if I go with an NAS configuration? I'm also thinking about a possible RAID configuration since I cannot replace most of these files if there's ever a drive failure. What solution would work best, and what should I expect all of this to cost? I greatly value user friendliness, quiet operation, and minimalism design/aesthetic. The less blinking lights, the better. And does this thing have to be connected to the router via ethernet? I have poor wifi coverage in some parts of the apartment due to thick plaster walls, so it would be ideal if the NAS could extend wireless coverage. I really have no idea how NAS works, so apologies for the noob questions!
