The 45 MB/sec and 95 MB/sec numbers are read speeds, in your card reader. You will need a USB 3.0 reader and port to achieve either maximum speed (USB 2.0 only runs maybe 30 MB/sec at most, regardless of how fast the card is). Read speed can seem important when you have a few hundred files to download.
For write speed in the camera, the write speed is less, and which depends on the card, and also on the camera model.
Here is the best data for write speed, actually tested in a D7000:
Rob Galbraith DPI: Nikon D7000
A Large Fine JPG in D7100 is around 12 MB. So if the write speed were 12MB/sec, it would take one second (after the shutter completed). A burst of five would take five seconds. If that is acceptable to you, you don't need faster.
Both the 45 MB/sec and 95MB/second are shown to write around 24MB/sec. If you need more, I think faster is not as yet available (not in SD format). The 95 card can go faster in a D800, but is limited by the D7000 camera.
A RAW file might be 20 to 28 MB, so you would feel a burst of five harder.
Video is SLOW, and is NOT a speed consideration. Nikon says (in the link you posted) that Class 6 is enough for video (6 MB/second). Video has the entire record time to write the file.
