In this guide, you will find the best memory cards for the Canon 6D II.
The new 6D II features only 1 x SD/SHDC/SDXC memory card slot, shoots 6.5 frames per second and records Full HD videos at 60fps. Nothing out of the ordinary, which is why it wasn’t tough picking the best card.
What to pay attention to?
- 6.5fps is relatively fast, which is why you don’t want a slow card as you’ll be waiting for the buffer to clear, thus missing out on lots of shots
- Full HD at 60fps is a standard today, and while most cards can handle it easily, it helps paying a little attention before buying and making sure the card has minimum speed recommended
Unless you mainly shoot in a studio with no external variables, you’ll want to make sure your memory card can get the job done quickly. This includes wedding, long exposure, action and portrait photography.
What Size & Speed?
The Canon 6D II can use UHS-I type of cards and you won’t see any benefit from UHS-II as the camera is not able to utilize those faster speeds (like most Canon and Nikon DSLRs today). You don’t have to spend too much here and are fine with cards at around ~$30 (for 32GB). You can see full specifications of the 6D II’s memory system here.
Speed Class of SD Cards
|Class 4||4MB/s||Too slow for most modern cameras. Skip it.|
|Class 6||6MB/s||A little bit better but unless you take 3 pictures a year, skip it.|
|Class 10||10MB/s||Good enough for most cameras with 20+ megapixels and Full HD video.|
|U1 (UHS)||10MB/s||Good enough for most cameras with 20+ megapixels and Full HD video|
|U3 (UHS)||30MB/s||Perfect for fast burst cameras, Full HD at 60fps and 4K video|
With 20 megapixels, the average JPEG file size is 6MB, whereas RAW is 25MB. You can check how many pictures you can store here.
These are the best 3 SDHC/SDXC memory cards you can get:
- SanDisk Extreme Pro 95MB/s UHS-I U3
- Lexar Professional 95MB/s UHS-I U3
- Transcend R95/W60MB/s UHS-I U3
SanDisk Extreme Pro 95MB/s UHS-I U3
The SanDisk 64GB Extreme Pro 32GB U3 is our favorite card, seeing as it’s inexpensive and provides writing and reading speeds near 90MB/s. It’ll handle the Canon 6D II’s burst mode and Full HD video with ease.
The speed makes it perfect for whatever you’re doing; fast bursts with large megapixel cameras, 4K video, let alone Full HD. It comes in 16GB, 32GB, 64GB, 128GB and 256GB sizes.
Lexar Professional 300MB/s UHS-II U3
The Lexar Professional 300MB/s UHS-II U3 offers faster speeds for both writing and reading files. We just said above that the Canon 6D II won’t benefit from it, and it’s true, but if you transfer a lot of shots almost every day, you’ll appreciate the much faster transferring speeds to your computer.
Don’t have a memory card reader that supports such speeds? Luckily you get a free Lexar UHS-II reader along this card that will greatly reduce the waiting time. You also get a free downloadable Imaging Rescue software. It comes in 32GB, 64GB and 128GB sizes. And in case you ever decide to upgrade to a newer model, chances are it’ll support UHS-II so you’re covered. We recommend this Lexar card only if you’re annoyed with your current slow sharing speeds.
Transcend R95/W60MB/s UHS-I U3
The most affordable on our list, yet still UHS-I, is the Transcend 64GB UHS-I U3. In terms of reading speed it goes up to 95MB/s, while for writing the maximum is 60MB/s.
Transcend, just like Lexar above, gives you the option of downloading their free image recovery program and they both work pretty good in most cases. It comes in 64GB, 128GB and 256GB sizes.

What Brand is the Best?
Your photographs and videos are stored on a memory card, so you should definitely not try to save any money here by buying from unknown, cheap brands. While you save a few bucks, you probably won’t even get the advertised speeds, and are at a bigger risk of losing your shots.
We see too many beginners choosing the cheap route here, but until you transfer your shots to a computer/online, this is where they’re stored at. You want the memory card to be the most reliable piece of your equipment!
