Thank you all for the advice! I went ahead and ordered the Synology!

Video/photo editing + large file storage. I’d just be interested to mount it as file system on my UNIX systems and use it just like a big drive.

I suppose that’s what I needed to hear. Thank you very much! Do you happen to know some NAS that does well at transcoding and is within this €1500 range?

Oh I’d say not a lot of data at the moment. I have two 14 TB disks which I use as replicas. So I have 14 TB of total capacity roughly. I think a 4-bay NAS is good enough for start
