EOS R5 Mark II High Burst Mode in RAW: Type B card needed?

[watash1965]

Once again, I need to reach out for help. I appreciate anyone who can share knowledge on shooting RAW in the normal high-speed continuous burst mode using my Canon R5 MKII.

Do I ned a Type B card to do this?

A good SD or CF type B will allow you to shoot H+. The type of card isn't really a limiting factor but the write speed will impact how fast your buffer will fill and need a pause to complete withing to the disk. 

@shadowsports and I just helped another member out that drills down into reliable cards and their speed that I think would be helpful.

No, you don't strictly need a CFexpress Type B card to shoot RAW in H+ mode on the EOS R5 Mark II. A fast SD card can work too, but a CFexpress Type B card will give you much better buffer performance and allow longer RAW bursts before the camera slows down.

@watash1965 ,

You must use CF Express type B cards in your R5 Mark II.  No other CF cards are compatible. 

For SD cards I would stick with UHS-II v60's or v90's < (my preference).  As mentioned in the other thread you posted, buy from a reputable source.
