The Canon 77D uses SD, SDHC, and SDXC memory cards. You will not gain any advantage from a UHS-I card, but it will be useable in a future camera upgrade.
Cards that are compatible with the 77D include any SD card with a storage capacity of up to 2TB. Bear in mind that older SD and SDHC cards will have slower transfer speeds, which may reduce the camera's capabilities.
Just want a compatible SD card? Here's my recommendation for the best memory card:
16 GB or 32 GB cards are inexpensive and large enough for photos.
64GB or larger cards are a better choice for video.
With a memory card, you can expand your creative horizons with a new lens. Take a look at the 8 Best Canon 77D lenses.
Best SD Cards
SanDisk, Lexar, and PNY are manufacturers that produce high-quality Memory cards. The best memory cards I have used have been the SanDisk Extreme Pro memory cards.
You do not need to buy a card from SanDisk for your Canon 77D. Just make sure the name is cool. That will mean you get fast transfer rates, dust resistance, and other professional features.
I have not had issues with Lexar Professional or PNY Elite Performance cards.
The problems I have encountered with memory cards has been when I have used cheap no-name brands. Being cheap increases the possibility of card failure or corrupted data.
If you want to save money, don't buy a cheap card. You will avoid problems by buying a professional-quality card with a reduced storage capacity.

Speed, Class, & UHS Ratings
The speed rating of an SD memory card is based on sequential read and write speeds. Card speed is essential for continuous shooting and video.
Slows memory cards can cause a drop in the number of continuous frames the Canon 77D can capture. This is due to the camera's buffer not being able to write data to the SD card quickly enough.
With video, a slow memory card can cause a sudden end to shooting. The video file might also end up being corrupted. If you are going to capture video, it is crucial the memory card you use meets the requirements of the camera.
Card read speed is important for file transfers to a computer or laptop. If you have cards that are full, a memory card with a fast read speed will save you time.
Speed Class Rating
The Class rating of a memory card is based on the sustained write speed. SD cards that have a write speed of at least 10MB/s will be labeled Class 10.
- Class 2 - 2MB/s
- Class 4 - 4MB/s
- Class 6 - 6MB/s
- Class 8 - 8MB/s
- Class 10 - 10MB/s or faster
Every name-brand card that you can buy today will be rated Class 10. You can check the class rating of a card by looking for a number inside of a C on the label.
Ultra High Speed (UHS)
The Ultra High Speed (UHS) bus can be found in SDXC And SDHC cards. UHS allows cards to achieve faster transfer rates.
There are 3 different specs. They are UHS-I, UHS-II, and UHS-III.
Look at the label to figure out the rating of a card. If the SD card has UHS a roman numeral I, II, or III will be on the label.
- UHS-I - Maximum transfer rate of 104 MB/s
- UHS-II - Maximum transfer rate of 312 MB/s
- UHS-III - Maximum transfer rate of 624 MB/s
Now that you what specs the camera needs you can see why the SanDisk 64GB Extreme Pro is the best Canon 77D memory card. This will also help you find an SD card for your future cameras.
