Latency differences should make a difference in responsiveness even compared to SSD over SATA. The bandwidth improvement is just gravy.

why not plug directly into memory bank? I am not using all 6 banks on my motherboard, and have no issue plugging 2 hd into the free slot.

A#1. Pinout on a lot of current SoCs includes I/O such as storage attach. So, sure. Soldering down to the PCB helps with the electrical characteristics, but that's not necessary for nonvolatile storage because of:

B#2. It's a different architecture?

Memory:
Storage <--- Bus ---> Controller
That is, all the smarts on on the SoC silicon.

HD:
Storage : Controller <---> Bus
That is, all the smarts are on the commodity silicon.

In particular, without knowing nothing about nonvolatile storage, I am pretty sure it is a less "flat" organization, logically, than system memory. Chunking the controller commands farther away from the storage strikes me as a dumb architecture for a stateful interaction.
