I posted a question about the best SD card for the D7100 a few days ago, and there were a lot of different opinions about the write speed of the camera, some saying the 95 mb/s card would be faster, some saying I wouldn't see any difference once the write speed of the card exceeded 30 mb/s

I decided to order the 95 mb/s cards anyway, worst that could happen would be I had 2 more high quality cards. They arrived today, so I decided to test them.

The test: I set the camera to manual mode, manual focus to avoid any camera delays. Shot bursts of 16 shots in high speed burst mode, RAW, and timed it with a stopwatch from the first shot until the buffer light cleared for shot 16. Each test was done 5 times and the times averaged, with 4 tests done: Two cards in, both cards writing (card 2 as backup) with both 95/mb/s cards, same test with both 45 mb/s cards, one 95 mb/s card in, and one 45 mb/s card in.
Here are the results:

Cards tested:
(2) Sandisk Extreme class 10 45/mbs
and
(2) Sandisk Extreme Pro class 10 95 mb/s

1. Two Extreme Pro 95 mb/s cards: average time 13.08 seconds
2. Two Extreme 45 mb/s cards: average time 23.18 seconds
3. One Extreme Pro 95 mb/s card: average time 9.95 seconds
4. One Extreme 45 mb/s card: average time 12.40 seconds

So, there you go, in case your interested as I was. I always use 2 cards with slot 2 as backup, and I was using the 45 mb/s cards - when I want max speed I will change card 2 to overflow only and I have switched to the 95 mb/s card, still not a D4s but going from 23.18 seconds for 16 shots to 9.95 is VERY noticeable...
