  • 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.

SD memory cards are now drastically less expensive than at the time the camera was originally made available.

With the price range staying so low, it will not make sense to choose anything but a high-quality SD memory card.

SanDisk Extreme Pro, Lexar Professional, and PNY Elite Performance cards are great. I have not had data errors or a card break with those SD cards.

Every one of the trouble I have encountered has been with no-name unbranded SD cards. Attempting to save around a dollar is not worth the cost if your T6I will not operate properly.

A sensible way to save money is to pick a smaller storage capacity SD card from a quality company. By doing this, you’ll know your shots are safe on the SD card.

The cards compatible in the Canon T6I are SDXC, SDHC, and SD. For best performance, be certain that your camera has the latest firmware.

The newest SDUC (Secure Digital Ultra Capacity) memory cards, are not able to be used with the T6I.

You need to know of the four types of Secure Digital (SD) memory cards that are available for purchase. You can identify the cards according to their capacity.

  • 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.

Below is a quick estimation of the volume of large JPEGs pictures you can be expecting to store on a SD memory card:

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

The speed rating of an SD card is based on the sequential read and write transfer speeds. Memory card write speed is critical for clearing the buffer for continuous shooting as well as recording video.

Slows cards can cause a drop in the number of continuous frames the Canon T6I can capture. This is because the camera’s buffer is not able to write data to the SD card quickly enough.

With video, a slow SD card can cause an abrupt end to shooting. The video file may also be corrupted. If you intend to shoot video, it is critical the SD card you use meets the required continuous write speed for video.

Read speed is important for transferring files to a computer. If you are filling up cards with images or video, a card with a fast transfer speed will decrease the transfer time.

The Class rating of a memory card is determined by the sustained write speed. Cards that have a minimum 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 brand of SD card that you can find today will have a Class 10 rating. You can check the class rating of a card by finding a number inside of the C on the sticker.

The Ultra High Speed (UHS) bus is a feature found in SDHC, SDXC, and SDUC cards. The UHS bus cards to achieve faster transfer rates.

Three separate versions exist. They are UHS-I, UHS-II, and UHS-III.

To know what the rating of a SD memory card, look at the label. A Roman numeral I, II, or III on the front of the memory card, that is the rating of the SD card.

  • UHS-I - Maximum transfer rate of 104 MB/s
  • UHS-II - Maximum transfer rate of 312 MB/s
