I used the 16Gb card in my Fuji X-T1 camera. I works very well. The X-T1 is capable of producing 8 RAW file images per second, and each RAW image is going to be about 33.6MB in size. The camera will buffer about 20 RAW files in the camera while it is writing them to the memory card. This calculates out to just under 270MB/s, so my hope was that this card would allow the X-T1 to acquire greater than 2 1/2 seconds of 8fps images. In theory, I should shave been able to shoot almost 5 seconds at 8fps before the camera switched to a slower frame rate. Unfortunately, this does not appear to be the case. In my simple testing, it appears that the camera can only write the to the card at around 100-150MB/s, which means that the buffer write time is reduced with this card, but it isn't eliminated. In all fairness to the X-T1, I know of no camera on the market today that is capable of shooting at 8fps until the card fills up. Perhaps an upgraded X-T2 in a couple of years will solve this problem.
This Reader/Writer is clearly the fastest way to read photos of video back into your computer from the camera.
Note however that i am reading into an iMac with a Fusion drive, which has a super fast internal flash assisted hard disk. Once I have the photos in my computer, backing them up via USB3 to another fast hard disk is much slower. So be aware that there can be lots of things in your photography acquisition, processing, and backup pipeline that will slow things down. A super fast card reader/writer and matching memory card are only one element.
Update added Performance Information:
Here are the results for the Extreme Pro 16 GB Secure Digital High Capacity UHS-3 card in the manufacturer specified UHS-3 SD card reader/writer.
Tests were run on a 2013 iMac with 16GB RAM and 3TB Fusion drive. The reader/writer was connected via USB 3 through an IOEGEAR USB 3 hub.
As you can see, the SD card is very fast for large block transfers, both read and write.

I would have giving the card more stars if it would have gotten 70MB/s. Other then that, the card does work just very slow for the price. So save your money and go with another brand.
It appears download speed is most dependent on card reader and the bus it is connected to according to reviews.
