Recommended SD Memory Cards For The T7i / 800D
Since the Canon T7i doesn’t use UHS-II technology, there isn’t really a need to spend the extra money on UHS-II cards, unless you want very fast transfer speeds to your computer from a UHS-II memory card reader.
The best performing and probably the best all around card for the T7i is the Sandisk Extreme Pro. Second place would be the Samsung Pro+ card, but any of the top performers functioned great in this camera, as to be expected – it’s a Canon, everything always just works.
Fastest UHS-II Memory Cards
Although the Canon T7i doesn’t support the extra speed you can get out of UHS-II memory cards, many people still like to use UHS-II to gain the performance when transferring from their cards to their computers. You will need a fast UHS-II memory card reader.

Fastest UHS-I Memory Cards
UHS-I are all around the best cards for the T7i, simply because they perform great and are very reasonably priced.
Canon T7i Frequently Asked Questions
Can I use Micro SD Memory Cards in the Canon T7i?
There is a lot of discussion about this with various cameras. Some people love Micro SD memory cards because of their versatility. They can shoot in camera, pop them into a phone and send shots to friends. Or swap cards between the camera and other devices, like action cameras or drones.
While Micro SD cards work fine, I personally don’t like them for my cameras. They are too small and easy to misplace. I’ve also had problems with the micro SD to SD adapter losing connection while shooting giving me errors.
What Cards Work Best For Video?
Since the Canon T7i is still only capable of shooting 1080p video, any decent memory card will work just fine.
My Card Isn’t Fast, What’s Wrong?
If you’re having some issues with your memory cards, here is a list of a few things that could be your problem.
- Sometimes cards are just bad. You can usually get them replaced without hassle and many have really good warranties.
- There are a lot of counterfeit cards out there. If you bought of Ebay, chances are you got duped. Stick with BHphoto, Adorama, Amazon or other trusted stores.
- Make sure the cards and connection pins are all clean and undamaged.
What Size Memory Card Should I Get, 32GB or 64GB?
I use 32GB cards if I’m just shooting photos and I rarely fill the cards. If I’m shooting photos with some videos here and there, I’ll need a 64GB card.
If I’m traveling and shooting on a card that I don’t clear for a few days I’ll usually fill up a 32GB card.
Best SD Memory Card Canon EOS T7i | Bottom Line
The Canon T7i can really take advantage of memory card performance, but the burst rate at only 6fps, isn’t all that great, but probably find for most people. This means you may not really need super fast cards since you may not be using the camera for a lot of burst photography. However, if you do shoot in burst mode a lot and want that buffer cleared quickly, then you may want to consider getting the Sandisk Extreme Pro cards. I personally always buy these anyway since they typically are the best.
