It is? How so? I don't see it anywhere outside their server and embedded products. The server-grade stuff isn't appropriate for "the little NAS boxes" used at home because of both expense and more importantly power consumption, and the embedded stuff just isn't really available to consumers (so it might be potentially great for a company like Synology that builds consumer-friendly pre-built NAS boxes running on proprietary software, but it's not useful to people building their own DIY NAS boxes running open-source software).
