Best Canon 90D Memory Cards

The Canon 90D uses SDXC, SDHC, and SD cards. To get the best performance from your camera, use an SD card with UHS-II.

Memory cards that can be used with the 90D include any SD card with a memory size of up to 2TB. A note of importance is that SD cards that do not have UHS-II will have slower transfer speeds, which can reduce the camera's capabilities.

Just want a compatible SD card? Here's my recommendation for the best memory card:

Sony M Series 128GB SDXC UHS-II memory card

Best value per GB for a UHS-II card.

If you will be shooting video, a 256GB card is a better choice.

Now that your camera is ready to go, you can expand your capabilities with a new lens. Take a look at the 8 Best Canon 90D lenses.

Best SD Cards

SanDisk, Lexar, and Sony are manufacturers that make high-quality Memory cards. The best SD cards I have owned have been the SanDisk Extreme Pro memory cards.

You do not need to purchase a card made by SanDisk for your Canon 90D. Make sure that the card has UHS-II. That will ensure you get the fastest read/write rates the camera is capable of.

I have not run into issues with Sony or Lexar Professional SD cards.

Any issues I have had with memory cards has been when I have used inexpensive brands. Not having a brand name increases the chance of data corruption or card errors.

If you are looking to spend less, don't buy a generic card. You will avoid problems by purchasing a name-brand SD card with a reduced storage capacity.

Speed, Class, & UHS Ratings

Card Speed

The speed rating of an SD card is determined by sequential write and read speeds. Card speed is important for video and continuous shooting.

Slows cards can cause a drop in the number of continuous images the Canon 90D can capture. This is due to the camera's buffer not being able to write data to the SD card fast enough.

When shooting video, a slow card can cause an unexpected end to the recording. The video file may also end up being corrupted. If you intend to shoot video, it is critical the SD card you use meets the requirements of the camera.

Read speed is nice to have for transferring files to a computer. If you have cards that are full, a card with a fast read speed will save you time.

Speed Class Rating

Example of where to find SD Card Speed Class
The 10 inside of the C means the card is Class 10.

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 are labeled 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 card that you can buy today will be rated Class 10. To check the class rating of a memory card, try to find a number inside of a C on the label.

Ultra High Speed (UHS)

Example of an SD memory card with a UHS-I rating.
The UHS rating of a card can be determined by a Roman numeral I, II, or III on the label of the card.

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 Sony M Series SDXC UHS-II is the best Canon 90D memory card. This will also help you find an SD card for your future cameras.
