I had a DS212j for about 10 years before I replaced it, and it was working just fine, so I sold it on ebay. It just couldn’t keep up with the transcoding plex that I was using it for. Heck, 7 of those years it was running on a shelf in my garage getting covered in dust, and spiderwebs.
I imagine a + model will last even longer than that.
