Slow buffering when shooting high burst mode with my 7DMarkii.....what is the fastest SD card?

[iris]

When shooting high burst mode with my 7D Mark ii, I am not getting optimum performance...the buffer fills fast and backs up ..so that I can't take any more shots...I have turned off the High NOise reduction setting altogether...I usually only have an SD card in the camera. I don't use the other card slot....is it because I didn't have the fastest SD card....For those of you who regularly shoot the 7D Mark ii, do you make a point to always shoot with a SAndisk SD 95 card...? Would i get better performance if I used the CF card slot or both?

OK...so i'll get my first CF card...So Peter there was nothing wrong with your information the first time around..

Don´t forget to check the write speed of the CF card. The SD card you wrote about from Lexar has a write speed of maximum 75 MB/s and a read speed of maximum 150 MB/s.

I feel I have bought a Volkswagen. However, I will be using my camera tomorrow to test out your theory that perhaps the number shown on the viewfinder is not necessarily the number of shots one gets before buffering. Also, I will take the advice offered here s out the better performance from the CF card. Thank everyone for your responses! !

I just shot some White Water Rafting action today using both my 1D4 & 7D2. The photos will be used commercially by the rafting company. Ran up against the buffer a few times with the 1D4 but not once using the 7D2 in a similar manner. Fast write speeds are the answer to your problem.
