The enclosure is likely to contain control electronics and perhaps more redundancy than a mobile device. Plus there's less need to go with full-on bleeding-edge chips in a larger enclosure. IOW. consider the 1TB measure generous and the 10TB one conservative.
That said, it seems 3D NAND is about to emerge, and if the price points drop as advertised, this may be at last be the sunset of spinning rust as a mainstream storage tech. If the tech evolves to use more aggressive cells (shorter-lived but can hold more), it may even find a use as a bulk storage medium provided its caveats are kept in mind.
