Data applies for 5d3 only

If you need the speed, Lexar 1000 seems to be the fastest.

Note that this is valid data only for the 5D3, since it does not support UHS1 etc.

With my 6D (which does support UHS-1) i get something much closer to the specified 90MB/S for the sandisk extreme pro SD cards. The difference between the trancend (20-ish MB/s ) and the sandisk extreme pro is from 4 or 5 frames to 20-21 before buffer runs full with my 6D.

Now theoretically CF can alwas be made better than SD cards, but in practice the problem is writing data fast to the flash memory.

At the moment the practical difference is within the cameras and not so much in the CF vs SD.

The 5D3 users should use Compact flash for burst-photography, while the SD cards will do for video. For users of newer cameras, the difference is not that great at all.
