Hi everbody,

I have been using SanDisk Extreme Pro 170mb/s in my R6 for quite some time and due to its deep buffer saved me some money on UHS-II cards. Now there are the new UHS-I cards with write speeds up to 140mb/s which would be a nice and affordable upgrade for me. Does anybody use these on the R6 (or other cameras) and can confirm some extended frame count due to its supposedly faster write times?

Thx

Q

May I ask what you shoot you need to machine gun your shutter so much it fills up the buffer? Faster cards are more important for video work then stills for most people.

... and high bandwidth video, at that, like hires, high-fps ALL-I, or RAW video.  2K 60fps IPB is not particularly demanding, and even 4K 60fps IPB only needs 30MB/s write speed.

I know that the R5 has video modes that absolutely require CFExpress B to even record, but I don't know if the R6 has any "needy" video modes that need faster SD cards.  Almost any modern SD card can be written to at least 45MB/s.  I bought a v10 Sandisk card, the slowest class currently produced by the big-name manufacturers AFAIK, in an emergency a couple of weeks ago, and it writes at 49MB/s and can be read at 145MB/s, according to CrystalDiskMark, as formatted in my R7.
