Not enough knowledge, in any of the areas involved, but my intuition makes me doubt the longtime security of these complexities, although i really appreciate the results. Or is there no need for trusting the firmware, if all the I/O is encrypted? I am fantasizing all these data patterns could combined with other information lead to the data-storage/-encryption equivalent of branch-prediction-exploits.. ..but maybe it's just half-knowledge combined with the fear-what-you-don't-understand.. ..and of course this wouldn't be in the first layer of attack.
