p.2 #1 · 5D4 - What Speed/Type of Memory Cards Should I Buy?
I haven't tried 4K myself, but on Page 356 of the manual there is a table that shows what cards are necessary to shoot movies of various quality, and there it says that a UHS-1 SD card that is 90MB/sec or faster will work to shoot 4K.

Thanks for the advice.
I've one last doubt: is it a real advantage to use one bigger file (using ExFat format cards) instead of several smaller files (Fat32) for editing purposes?

FWIW: I recently registered for email notifications at B&H for their specials, and this morning got one mentioning the Lexar 32GB 1066 CF cards (2-pack) at a good price. With the 30MP 5DIV files, I prefer the 64GB cards, but these will work for my upcoming trip to India.
