I am unsure where I stumbled across this card but I am wondering if it would help/cure the buffer issue?
SanDisk 64GB Extreme PRO SDHC/SDXC UHS-II Memory Card 4K Full HD
I haven't tried the 'UHS-II', but the same card in 'UHS-I' was a huge improvement over my slower (Ultra series) sandisk card. You need a really fast card to get the camera up to its hardware limit. After that, or above that, you won't see any buffer improvement. But, the Extreme Pro's are the best cards for the D7100.
