The Sony G series memory card is Sony's fastest UHS-II memory card with read speeds rated at 299 MB/s and write speeds rated at 300MB/s. The Sony G UHS-II cards are great cards for any UHS-II cameras. They work great for Fujifilm and Sony cameras and are one of the best memory cards you can buy for the latest Sony UHS-II cameras.

ADATA is a flash manufacturer out of Taiwan and is new to the UHS-II memory card game. They've yet to really gain in popularity but their cards perform at the top of the charts for UHS-II speeds and easily match the performance of Sandisk, Lexar and Sony UHS-II cards. If Adata can prove reliability they could be a great alternative to Sandisk once Lexar is no longer around.

Fujifilm has stepped into the flash memory card game with their UHS-II SD memory cards designed to be used with their UHS-II compatible cameras; like the X-T2 and the X-Pro 2. While the specs look promising the card performs almost identical to the Transcend UHS-II card. This makes me believe it's just a relabeled Transcend card as I don't believe Fujifilm does any flash manufacturing themselves. Of course, I could be wrong. That being said, the Transcend cards are great and so is this Fujifilm Elite II card. It's not as fast as some of the other cards out there in terms USB 3.0 write speeds, but its in-camera performance and its USB 3.0 read speeds are fantastic.
