Best SD Card for Canon EOS R10 ?

Get SanDisk Extreme PRO UHS-II V90 SDXC.

Get an SDXC card with UHS-II interface that's rated at V60 or V90 - Canon recommends at least V60.

My top pick is the SanDisk Extreme Pro V90 - it handles everything the R10 throws at it including the 23fps burst mode and 4K recording. For casual shooting and videography, V60 cards work just fine, so don't feel like you need to go V90 unless you're doing serious high-speed work.

Besides SanDisk, Lexar UHS-II V90 SD card is also great for EOS R10.

Noted!

To add to the point above, you might want to consider looking at some mid-range options if the high-end stuff feels too pricey for your budget. The R10 is a beast but you dont necessarily need to break the bank on memory. I would suggest checking out the Kingston Canvas React Plus 128GB SDXC UHS-II. It usually comes with a free reader and hits those V90 speeds for way less than the bigger brands. If you're really looking to save, the Sony SF-M Series UHS-II V60 128GB is a solid bet too. Just be careful with those random cheap brands you see on Amazon tho... sticking to Kingston or Sony is way safer for your photos. Make sure to double check the seller ratings before you pull the trigger because there are a lot of fakes floating around lately.

I highly recommend the SanDisk Extreme PRO SDXC UHS-II card. It offers read speeds up to 300MB/s and write speeds up to 260MB/s, which is more than enough for the R10's capabilities. This card will handle 4K video recording and high-speed burst shooting without any issues. Plus, it's reliable and comes with a lifetime warranty.

For primarily storing photos, 256GB is excessive. Consider purchasing two 128GB SD cards instead. This provides a backup if your main card fills up. Recommended brands include SanDisk Extreme and Lexar Pro, both known for their reliability and performance in photography applications.

The UHS-II V90 SD cards are highly recommended.

Any UHS-II V60 card or better will work great. I'm using the ProGrade Digital SDXC UHS-II card and it keeps up perfectly with 23fps bursts and 4K video. No complaints after 6 months of heavy use.

For SD cards, Canon recommends at least a V60 card. A V90 will also work if you find a good deal.
