Clearly the fastest cards for the Canon 7D II are the CF cards and in this test the Lexar 1066x came out on top at 102MB/s. But all of the high end CF cards were very close. 

SD memory card speeds are still very quick running at 72 MB/s. 

 

Best CF Memory Cards For the Canon 7D II

Here are the top fastest CF memory cards for the Canon 7D II. The results were so close that any of the cards will perform noticably the same and in fact, if I ran the test several more times I could see the order alternate since I only take an average of three tests per card.

  • Toshiba 1066x 32GB – Amazon
  • Transcend 1000x 32GB – Amazon

 

Best UHS-II Memory Card

The Toshiba is the fastest memory card if you’re using UHS-II. But only marginally faster than the Lexar.

Best UHS-I Memory Cards

The fastest UHS-I memory card is the Sandisk. But Kingston, Samsung and Sony all come very close.

Best Memory Card Reader

Best SD / CF Memory Card Reader

 

 


SD Memory Cards – UHS-I  vs UHS-II


Which is better, UHS-I or UHS-II for the Canon 7d II? From the results, very little speed is gained in camera by using a UHS-II card; this is because this camera only supports UHS-I memory cards. However, file transfer via USB 3.0 is much faster with UHS-II cards.

The UHS-II Sandisk Extreme Pro, the Kingston, Samsung Pro and the Sony are the fastest memory cards for the Canon 7DII. For the price the Sony is often times less expensive and you get very close to the same performance.

Should You Use UHS-II Memory Cards For The Canon 7DmkII?

This is question you should consider. A lot of people actually do use UHS-II cards for their camera simply because they can get faster file transfer speeds to their computer. If file transfer speeds from card to computer are a problem for you then you might want to consider this option.

 

 


CF vs SD Cards – Which Is Better?


Clearly the CF cards are much quicker than SD cards in the Canon 7D II. However, if you’re just casually shooting you might not notice the difference in speed unless you’re doing a lot of bust shooting where you’re constantly filling the buffer. With that being said, SD cards are more affordable and more practical for the casual shooter. However, the Pro that runs dual memory cards will have to get a CF card and SD card.

 

 


Canon 7Dmkii CF & SD Card Configuration Options


If you have a CF card and an SD card there are a few really cool ways you can configure them to work together.

 

CF Primary SD Backup

Probably the most useful configuration is to use your CF card as a primary and have backups stored to the SD card. This will however bottleneck your speeds to your slowest card, most likely the SD card you use, so be sure if you’re using backup, that you get the fastest sd memory card you can.

 

CF Primary SD Card Overflow

Another option, is to use your CF card as a primary and when that fills up the camera will overflow to the SD card. This again will slow down write speeds to the SD card once the camera makes the switch to slot 2.

 

 


Best Memory Cards For The Canon 7D II Conclusions


So should you buy CF cards or SD cards?

For casual shooting I would just go with SD cards, they’re cheaper, smaller, they usually plug right into your laptop or computer and overall are much easier to deal with. But if you’re a pro and need to run a lot of burst shooting or need a backup, then the CF card is most likely what you’ll need.

 

As far as speed, most of the time I find you don’t really notice a difference in cards speeds when shooting in real world situations as long as you have a card that is decent with camera write speeds. So with UHS-II cards, you probably should consider the Lexar x2000 over the Toshiba because it has much better USB 3.0 read speeds than the Toshiba.

Use this test chart to determine what’s best for you. There are a lot of options at a lot of different prices. Good luck!
