I've had a DS411j for a really long time, well over a decade. I use it for backups and extra storage, and I have been perfectly happy with it during this time.
I recently got an e-mail from Synologi that said that these models would no longer receive updates, which is sad but quite understandable.
Should I continue to just run my old system for as long as it lasts, or is that a stupid idea that will end badly? If the latter, what would be the recommended model to upgrade to? I just want "some storage space", so everything fancy would be quite wasted on me. That said, I'm not too price sensitive, so I'd rather pay a bit more for something that will again last 10+ years, rather than slightly
