I've got my opinions about all you've mentioned, but, at least the 400GB Micro SD cards should be compatible with both the QP1R and QP2R, as the standard should currently be able to handle as high as 2 terabyte Micro SD cards.
@moedawg140 I would like to hear your opinions if your so inclined and I hope your correct about 400GB cards but will have to wait on that until prices come down a bit.
