The numbers I posted were for UFS. Correct, the numbers I provided were for msm8998 UFS... Basically, it looks like sdm845 UFS is 4x faster than msm8998 UFS using upstream. Which is surprising (may depend on specific Flash chip in use though). Would be good if somebody with both boards could post numbers. I'll try to post "fresh" numbers when I can. Regards.
