Excerpt: I was looking to improve on the continuous exposure frames per second on my Nikon D7100. After the buffer is full (~6 frames shooting RAW) the camera has to write to the card as it shoots. I have been using SanDisk Extreme 16GB 45MB/s (sdhc 1 class 10) and getting about 44MB/s.
Beware: 280 MB/s only achievable with a UHS-II reader

Excerpt: This card has additional contacts on the back which are not used by my GH4 camera but are used by a UHS-II reader to obtain the rated performance. First, if you have a GH4, the requirement is 200 Mbps which is only 25 MB/s. Even a UHS-I card should be sufficient.
Pros: Durable, Fast Computer Interface, Lightweight, Reliable
Cons: Poor Value For Camera Use, Requires Reader For Perf
