Best Canon EOS M6 MKII SD Memory Card

SD, SDHC, and SDXC memory cards are compatible with the Canon M6 MKII. Continuous shooting and video need SD memory cards with high write speeds to the card.
The SD memory card you go with is a considerable effect on the functionality of your camera.
Don’t care about the technical details? Here’s my recommendation on the card for use with the Canon M6 MKII:

- 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.
Best SD Cards
Memory cards have dropped in cost the time since the release of the Canon M6 MKII.
Due to the price range being cheap, it would not make financial sense to choose anything but a pro-level SD card.
SanDisk Extreme Pro, Lexar Professional, and PNY Elite Performance cards are excellent. I have not experienced unusable data or a card failure with any of those SD cards.
All the issues I have experienced has been when using no-name unbranded SD cards. Hoping to save around a buck isn’t worthwhile if your M6 MKII is likely to have trouble.
To save money, get a lower storage capacity SD card from a quality supplier. By doing this, you will know your photographs are secure on the memory card.

Canon M6 MKII SD Card Compatibility
The only memory cards compatible with the Canon M6 MKII are SDXC, SDHC, and SD. For best performance, ensure your camera is using the latest firmware.
The newest cards, SDUC (Secure Digital Ultra Capacity), aren’t able to be used in the M6 MKII.
You should be aware of the 4 types of Secure Digital (SD) memory cards that exist. They are separated by 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.
Image Capacity

Here’s a fast approximation of how many max-quality JPEGs photos you can expect to store on a SD memory card:
- 16GB - 4,640 images
- 32GB - 9,280 images
- 64GB - 18,560 images
- 128GB - 37,120 images
Speed, Class, & UHS Ratings
Card Speed
The speed rating of an SD memory card is classified by the sequential read and write speeds of the card. The continuous write speed of a SD memory card is essential for clearing the camera buffer for continuous shooting and recording video.
A slow memory card can cause a reduction in the number of continuous photos the Canon M6 MKII can capture. This is because the buffer in the camera is not able to write to the card fast enough.
When shooting video, a slow card can cause a sudden end to the recording. The video file could also be corrupted. If you intend to shoot video, it is crucial the SD card you use meets the requirements of the M6 MKII.
Read speed is nice to have for file transfers to a computer. If you have cards that are full, a memory card with a fast transfer speed will reduce the transfer time.
Speed Class Rating

An SD memory card receives a Class rating based on its continuous write speed. SD cards that have a minimum 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 SD memory card that you can find will be Class 10. You can locate the class rating of a SD card by looking for a number inside of a C on the front label.
Ultra High Speed (UHS)

The Ultra High Speed (UHS) bus is a feature often found in SDUC, SDXC, and SDHC memory cards. The UHS bus makes it possible offers a way to improve file transfer rates.
Three separate specifications exist. They are UHS-I, UHS-II, and UHS-III.
To find the rating of a memory card, look on the front of the card. If the memory card has UHS, a Roman numeral I, II, or III can be seen on the front of the SD memory 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
