I wonder when Synology will release a new consumer 4-bay NAS to replace the DS918+. Feels like it's a bit old and whilst the 1019+ came out which is pretty much same NAS with one more drive bay (and more RAM), it's largely same same. I've been itching to upgrade my DS216j to a 4 or 5 bay, but it just doesn't feel like enough of a leap given it's already a couple of years old and surely another generation is coming soon.
