That is a pretty strong assumption, isn't it?  Also you seem to be
assuming that the controller<->disk protocol (some internal, unknown to
mere mortals, mechanism) is equally powerful than the host<->controller
(SATA, SCSI, etc).

I'm lost whether this thread is about what is possible with current,
in-market technology, or about what could in theory be possible [if you
were to design "open source" disk controllers and disks.]
