I got a Synology 218J some years ago from scan.co.uk. mine is the unpopulated version so I had to bung in a couple of drives. Can’t recall what they are - probably WD of some flavour.
The whole thing has been very reliable and was easy to set up. I use it to stream flac files and video. It just sits in the study and does it’s thing without fuss. It even updates itself on its own.
Why scan.co.uk? I live nearby and they are handy. I imagine buy from anywhere you fancy really.
Why a Synology? Somebody on another place (the Big Tent) recommended them and did a “how to” “back of a fag packet guide” and he used a Synology so I just followed suit. Was that Gyroscope? Whoever it was, ta.
