OK, looking at a NAS system and have been reading up about what it is and if it's for me and think I got my head round it all other than what exactly raid is, but I think I can look at that further down the line. So, currently, there are 3 phones, 2 ipads, sons gaming PC upstairs, wifes macbook air, my macbook pro and another pc in the living room i use for torrents / movies then accessed via plex and cast to the TV. I was initially thinking of a 2 bay synology nas with 2 WD red drives with one mirroring the other? Data wise Im the data hog as the pc used for movies / torrents has a maximum 1tb drive in there and it's getting full, but it's taken some time for that to be fair, plus then theres my photos but again, probably about 500gb only over the last 5 years. So I want something on the network that can be a backup solution plus use for the torrents / movies and access via plex. Am I talking complete rubbish or does this make sense to those that have experience with NAS? Any help would be very much appreciated.
