You can ruin the performance of your camera by using the wrong SD card.

Don't want to read the tech jargon? This is my suggestion on the memory card for use in your Canon EOS M6 MKII:

SanDisk Extreme Pro 128GB UHS-I SD Card

Best SD Cards

In the time since the intro of Canon EOS M6 MKII, the cost of memory cards has dropped.

Seeing as how cheap the price range are, it would not make financial sense to purchase anything other than a professional-quality memory card.

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

Every complication I have had has been when using cheap unbranded SD memory cards. Seeking to save a small amount of money isn't worth it if your EOS M6 MKII is not going to function properly.

A savvy way to spend less money is to purchase a smaller storage capacity card from a quality manufacturer. By making that choice, you will know your photographs are safe on the SD card.

Speed, Class, & UHS Ratings

Card Speed

Speed ratings of an SD card is classified by the sequential read and write speeds. The speed of a card is critical for continuous shooting in addition to video.

Slows cards can cause a decrease in the number of continuous images the Canon EOS M6 MKII can take. This is because the camera's buffer will not be able to write to the SD card quickly enough.

When recording video, a slow card can cause recording to stop. The video file may also end up being corrupted. If you intend to shoot video, it is important the card you use meets the minimum requirements of the EOS M6 MKII.

Read speed is important for file transfers to a computer or laptop. If you have cards that are full, a SD card with a fast transfer 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 continuous write speed of a memory card is represented by the Class rating. SD cards that have a write speed of 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 brand of memory card that you can find today will have a Class 10 rating. You can verify the class rating of a SD memory card by finding a number inside of a C on the sticker.

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 bus (UHS) is often found in SDUC, SDXC, and SDHC memory cards. The UHS bus memory cards to achieve faster write speeds.

There are three separate versions. They are UHS-I, UHS-II, and UHS-III.

To figure out the UHS rating of a SD card, look on the front of the card. The presence of a Roman numeral I, II, or III on the front of the card, that is going to be the rating of the 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
