The Canon EOS R1 is already making many professional photographers and videographers salivate. A high-end mirrorless body, it promises exceptional image quality, a blazing frame rate, and breathtaking video capabilities. But to get the most out of this competitive beast, you need to come with a memory card that is up to the task.
In this article, we explain how to choose the right SD card for the Canon EOS R1, which models to buy with your eyes closed, and why this technical detail can make all the difference in the field.
Why choose the right SD card for the Canon EOS R1?
The Canon EOS R1 is designed to capture very high-speed bursts and shoot in 8K. This means that the files produced are heavy, and the recording rate is very demanding. A poor quality SD card can slow down your camera, cause writing errors, or even stop recording in the middle of the action.
The right choice of card therefore allows:
- Smooth RAW burst capture
- Stable recording in 8K or 4K 120fps
- Fast unloading of your files
- Better durability and protection of your data
What criteria should be taken into account?
Here are the key points to look out for:
- Write speed : at least 90 MB/s for 4K, V60 or V90 ideally
- Read speed : important for transferring to your computer
- Capacity : 128GB for light outputs, 256GB or 512GB for 8K video or long photo series
- Format : The Canon EOS R1 is compatible with SD UHS-II and CFexpress Type B (as per specifications)
- Robustness : waterproof, resistant to shocks, X-rays, heat

What about CFexpress Type B cards?
The Canon EOS R1 could offer a dual slot: SD UHS-II and CFexpress Type B (as on the R5 and R3). CFexpress cards are even faster than SD cards: up to 1700 MB/s. If you’re shooting 8K RAW video, they become almost indispensable.
But be careful: they are more expensive and do not all have the same compatibility. To be reserved for a really professional use.
Our practical advice for using your SD cards properly
- Format in the device : it avoids file errors
- Don’t unload your photos in the middle of the action : wait for the writing to finish
- Always have a backup card : two 256 GB cards are better than one 512
- Store them in a hard case to protect them
FAQ – Your most frequently asked questions about SD card for the Canon EOS R1
What capacity should I choose for 8K video?
A 512 GB card is recommended for stress-free filming, especially if you shoot in RAW or long sessions.
Can a UHS-I card be enough?
For standard 4K photo or video, yes. For 8K or extended burst, it’s better to upgrade to UHS-II.
Are old SD cards compatible?
Yes if they are UHS-I or II, but they will limit performance. Avoid low-end UHS-I.
Why does my card saturate quickly?
RAW and 8K are very demanding. Switch to 256 or 512 GB cards if you shoot a lot.
Can I mix SD cards and CFexpress?
Yes, if the device has a double slot. Practical for dissociating photo/video or working with a backup card.
