I got it for my Canon R5c. I like to dual record, and need a fast high capacity card for the SD slot, and this worked perfectly so far. I don't shoot 8K so I haven't texted that, but shot all day with no issues.

Specifically regarding the 128GB SD card, is the max write speed 200 MB/s or 275 MB/s? Specs and image have different info.
I just read the information on the ProGrade website, and it seems to contradict the answer provided by B&H here.
https://shop.progradedigital.com/products/sdxc-uhs-ii-v90-300r-iridium-memory-card?variant=49605908627703
They list a write speed to be 200 MB/s for the 128 GB SD card only and 275 MB/s for all larger capacity cards.
If there's something I'm missing, please let me know. Thanks.
