Synology’s telegraphed moves toward a contained ecosystem and seemingly vertical integration are certain to rankle some of its biggest fans, who likely enjoy doing their own system building, shopping, and assembly for the perfect amount of storage. “Pro-sumers,” homelab enthusiasts, and those with just a lot of stuff to store at home, or in a small business, previously had a good reason to buy one Synology device every so many years, then stick into them whatever drives they happened to have or acquired at their desired prices. Synology’s stated needs for efficient support of drive arrays may be more defensible at the enterprise level, but as it gets closer to the home level, it suggests a different kind of optimization.
This is why I chose an ASUS nuc + external bay-storage for my home networking needs, felt like synology NAS would be a limiting factor.
So you built your own NAS, then. NAS is just an acronym, “Network Attached Storage”. Not a singular line of products.
That said - I also feel the same way about Synology and the other “all-in-one NAS” brands. Expensive for what they are, which is essentially an incredibly cheap PC with a built in toaster. I built my NAS out of a 2014 Mac Mini (running OMV) and a Sabrent USB-C 4-bay drive dock, and even full of WD Reds, that entire rig is literally half the price of a DS920+. And more powerful.
