Best Canon 77D SD Memory Card

SDXC, SDHC, and SD memory cards were meant to be compatible with the Canon 77D. Fast write speeds are a critical aspect for continuous shooting and video.

An inadequate memory card can mess up the overall performance of your camera.

If you are in a hurry, here’s the best SD card you can buy for the Canon 77D:

  • UHS-I, U1, and Class 10 Speed Rating. Can sustain 10MB/s write speeds.
  • Excellent choice for photos.
  • Capable of recording Full HD (1920x1080) Video.
  • Inexpensive with more than good enough performance.
  • Larger capacities are available for a reasonable price.

Memory cards are now significantly less expensive than when the camera was initially introduced.

With prices staying low, it will not be sensible to pick anything besides a high-quality SD memory card.

The best SD cards I have owned have been the SanDisk Extreme Pro, Lexar Professional, and PNY Elite Performance models. I have not encountered a card failure or unusable data with those SD memory cards.

Every single issue I have experienced has been due to low-cost unbranded memory cards. Trying to save around a dollar is not worthwhile if your 77D will not operate as it should.

To save money, purchase a smaller storage capacity SD memory card from a high-quality manufacturer. By making that choice, you’ll know your images are secure on the SD card.

The cards compatible with the Canon 77D are SD, SDHC, and SDXC. For best performance, ensure that your camera has the most up to date firmware.

The newest memory cards, SDUC (Secure Digital Ultra Capacity), will not be able to be used in the 77D.

You need to be aware of the 4 different types of Secure Digital (SD) cards that can be used. They are split up by their storage size.

  • SD (Secure Digital) - 128MB to 2GB.
  • SDHC (Secure Digital High Capacity) - 4GB to 32GB.
  • SDXC (Secure Digital eXtended Capacity) - 64GB to 2TB.
  • SDUC (Secure Digital Ultra Capacity) - 4TB to 128TB.

Here is a quick estimation of the total number of max-quality JPEGs pictures you can expect to be saved on a SD card:

  • 16GB - 4,640 images
  • 32GB - 9,280 images
  • 64GB - 18,560 images
  • 128GB - 37,120 images

Speed ratings of an SD memory card is determined by the sequential write and read transfer speeds. SD card speed is essential for clearing the buffer for continuous shooting as well as recording video.

A slow memory card can decrease the number of continuous photos the Canon 77D can capture. This is because the camera’s buffer will not be able to write to the memory card fast enough.

When recording video, a slow SD card can cause an unexpected end to shooting. The video file may also be corrupted. If you intend to shoot video, it is essential the card you use meets the minimum requirements of the 77D.

Read speed is nice to have for file transfers to a computer. If you are filling up cards with images or video, a SD card with a fast read speed will save you time.

SD Card Speed Class

An SD memory card receives a Class rating determined by its continuous write speed. Cards that have a minimum write speed of 10MB/s are rated as 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 memory card that you can buy online will be Class 10. You can locate the class rating of a SD memory card by searching for a number inside of a C on the sticker.

The Ultra High Speed (UHS) bus is often found in SDUC, SDXC, and SDHC cards. The UHS bus cards to have increased write speeds.

Three different specs have been created. The three are UHS-I, UHS-II, and UHS-III.

You can figure out the rating of a card by reading the front of the card. If there is a Roman numeral I, II, or III on the front of the SD card, that is going to be the rating of your SD card.

  • 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
