Been thinking about sorting out a NAS for over a year now and finally decided to make the jump. I did consider building my own using something like FreeNAS but I saw other threads that made me realise right now I just want something that I can set up and leave going and it'll be fine. No need to be manually updating things when new releases/patches arrive etc. From what I can gather while there are other options Synology seems to be the clear favourite. I've decided I want to get a 4 drive one and use 8TB WD Red HDDs. Main use will be media storage and streaming over my home network. There would usually be 2 devices connected (rare occasions this could be 3), either PC's or Pi's for the most part but there may be a rare occasion where a mobile device would be used. I've had a look around, looked through threads here as well as other places and read a few articles, the consensus seems to be that the absolute best choice for me would be the DS918+. I just wanted to check that this is right and ask a few quick questions. 1. If I start with just 2 drives, when I want to add more (same size/model) is it just a case of sliding them in and the NAS detects them and adds them to the pool? 2. I'm not so bothered with backing up what's on there, but if I wanted to what would be the best set up? 4 drives in RAID 5? 3. I currently use emby but it seems plex has a built in app for synology, would it be worth making the switch? I've never used plex and emby does everything I want but for the sake of ease I wanted to know. Thanks in advance for any help!
