Best Canon Rebel T2i Memory Cards

The Canon Rebel T2i can only use SDXC, SDHC, and SD memory cards.

Compatible memory cards for the Rebel T2i include any SD card with a memory size of up to 2TB. You should be aware that older cards will have slower transfer speeds, which could reduce the camera's performance.

Don't care about technical specs? Here's my recommendation for the best memory card:

SanDisk 64GB Extreme PRO SDXC Card

  • Best value for the money.
  • Transfer speeds up to 170MB/s.
  • Excellent reliability.
  • Temperature-proof, waterproof, shock-proof, and X-ray-proof.

Once you have a working memory card expand your camera's capabilities with a new lens. Take a look at the 8 Best Canon Rebel T2i lenses.

Best SD Cards

SanDisk, Lexar, and PNY are the brands that produce the best Memory cards. The best memory cards I have owned have been the SanDisk Extreme Pro SD cards.

You do not need to buy a card from SanDisk for your Canon Rebel T2i. Just make sure the name is impressive. That will ensure you get fast read/write rates, shock resistance, and more features.

I have not run into issues with PNY Elite Performance or Lexar Professional memory cards.

When I have had problems with SD cards has been when low priced no-name brands were used. Being cheap increases the possibility of card errors or data corruption.

If you are looking to spend less money, don't buy a cheap card. You will avoid problems by purchasing a name brand memory card with a smaller capacity.

The Canon Rebel T2i can use SD, and SDHC cards.

Secure Digital (SD) memory cards come in four different specifications. Each new card spec increases the maximum storage capacity and transfer speeds of the card.

  • 16GB - 4,640 images
  • 32GB - 9,280 images

Speed, Class, & UHS Ratings

Card Speed

The speed rating of an SD memory card is based on sequential read and write speeds. Card speed is very important for video and continuous shooting.

A slow SD card can cut down the number of continuous frames the Canon Rebel T2i can take. This is because the camera's buffer is not able to write to the SD card fast enough.

When shooting video, a slow card can cause the recording to stop. The video file could also be corrupted. If you intend to capture video, it is essential the card you use meets the requirements of the camera.

Card read speed is nice to have for file transfers to a computer or laptop. If you are filling up cards with images or video, 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 an SD card is related to the sustained write speed. Cards that have a write speed of at least 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 brand name card that you can purchase online will have a Class 10 rating. 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)

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 SDHC and SDXC cards. UHS allows for faster data transfer rates.

There are 3 separate specifications. They are UHS-I, UHS-II, and UHS-III.

You can find the rating of a card by checking the label. If the memory 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 know why the SanDisk 64GB Extreme Pro is the best Canon Rebel T2i memory card, you'll be able to pick out the best SD card for any future camera.
