I think we can all agree that "NAS" for consumers is a marketing term, like "atomic clock". Anyone who works in an office with a NAS may come to admire its functions, and want the same experience at home.

When I think of NAS, I think of Network Appliance. Even in the mid-90s they were already well-known as the makers of the most formidable turnkey NAS that an enterprise could have. They are so awesome and specialized that I never even worked near one. Their systems were called "filers" and they have proprietary filesystems with proprietary kernels and CLI, that present with an NFS interface, among other things. The Filers are blazingly fast and ultra-high-capacity.
