Best Canon PowerShot Digital Camera Memory Card

The Canon PowerShot G10 uses SD memory cards. 32GB is the biggest capacity SD card that can be used in the PowerShot G10. MMCplus and MultiMediaCard (MMC) can also be used.

SD memory cards described as SDUC or SDXC are not going to work correctly in the PowerShot G10. These cards can be easily avoided as they are 64GB or larger in size.

Don't want to read the technical specs? Here's my suggestion on the SD card to use in your Canon PowerShot G10:

SanDisk Extreme Pro UHS-I SDHC Memory Card

SanDisk Extreme Pro 32GB SDHC

  • Best value for the money.
  • Read speeds of up to 95MB/s; write speeds of up to 90MB/s.
  • Shock-proof, temperature-proof, waterproof, and x-ray proof.
  • UHS speed Class 3 (U3) and UHS video speed Class 30 (V30).

64GB or larger cards are not compatible with the camera.

Recommended PowerShot G10 SD Cards

Down below are memory cards that will function correctly with the PowerShot G10. With any of the cards listed below, you will not have to stress out over sluggish capabilities or SD card errors.

SanDisk Extreme Pro UHS-I SDHC Memory Card

  • UHS-I technology for a read transfer speed up to 633x (95MB/s).

Best SD Cards

Lexar and SanDisk both manufacture high-quality memory cards. Avoid buying cards from inexpensive third-party brand names.

Memory card errors, such as a complete loss of all of your photographs caused by data corruption, is more probable to take place with cheap cards. The reduction in build quality is not worth the minimal cost savings.

Buy a reduced capacity memory card if you happen to want to decrease costs. They tend to be a bit lower in cost and you will not have to be worried about the SD card failing.

Do not forget, SD card issues are not common. Over the years, I have only experienced 2 cards fail. The two memory cards were previously owned third-party cards that were bundled with the purchase of pre-owned cameras.

Canon PowerShot G10 SD Card Compatibility

4 separate specifications of Secure Digital (SD) cards are currently being made. The Canon PowerShot G10 is limited to using SD memory cards. The benefit is that there is an improvement in the read/write speeds and max storage capacity with the release of each updated specification.

Secure Digital memory card readers are backward compatible. A card reader built into a digital camera that can use SDXC cards will also be able to use SDHC and SD memory cards.

The Canon Rebel T3i can use larger capacity SD cards. There are also many great lenses for the Canon Rebel T3i for portrait photography and every day photography.

The Canon PowerShot G10's card reader can only read the initial two SD card specs. SDUC or SDXC memory cards won't function correctly.

  • Secure Digital (SD) - These memory cards have a maximum capacity of 2GB and are compatible with the PowerShot G10.
  • Secure Digital High Capacity (SDHC) - The capacity of these memory cards range from 4GB to 32GB and are also compatible with the PowerShot G10.
  • Secure Digital eXtended Capacity (SDXC) - The capacity of these memory cards range from 64GB to 2TiB.
  • Secure Digital Ultra Capacity (SDUC) - The capacity of these memory cards range from 4TiB to 128TiB.

Canon PowerShot G10 Memory Card Full Error

Trying to use a memory card that has a storage capacity of 64GB or larger in size in the PowerShot G10 results in the point and shoot camera to show an error message.

Use a card with a capacity of 32GB or less to rectify the error.

If you are using an SD memory card that is 32GB or smaller capacity, and the card is not working, format the card while it is in the camera.

Speed, Class, & Capacity

SD Card Image Capacity

Here is an estimation of how many large JPEGs you will be able to keep on an SD card.

  • 4GB - 1920 images
  • 8GB - 3840 images
  • 16GB - 7680 images
  • 32GB - 15360 images

Memory Card Speed

The speed rating for SD cards is established by sequential read and write speeds. The speed of the SD memory card is important when many images need to be written or read from the SD memory card.

SD Card Speed Class Rating

Example of where to find SD Card Speed Class
This is a Class 10 SD memory card as shown by the '10' inside of the 'C'

The Class speed rating of an SD memory card is dependant on the sustained write speed of the card. A Class speed rating of 2 means that the SD card can sustain a write speed of at least 2MB per second.

  • Class 2 - 2MB/s
  • Class 4 - 4MB/s
  • Class 6 - 6MB/s
  • Class 8 - 8MB/s
  • Class 10 - 10MB/s

The maximum rating an SD card can obtain is Class 10. There are SD memory cards that are considerably faster than 10MB/s. Those memory cards use other technologies, such as UHS (Ultra Highspeed Bus), which have different rating specifications.

Sustained write speeds of 2MB, 4MB, 6MB, or 8MB per second means the card has a speed class of 2, 4, 6, or 8. Cards that have write speeds of 10MB/s or faster are rated as Class 10.

MultiMediaCard Compatibility

The MultiMediaCard standard was introduced by Siemens AG and SanDisk in 1997. MMC cards are comparable in dimensions to an SD card, but they are a little bit thinner.

Only the 1st two generations of MMC memory cards will function correctly in the Canon PowerShot G10. Suitable memory cards will be branded as MMC or MMCplus. Later generations will not work with the Canon PowerShot G10

I would not advise looking for any MMC cards. Manufacturers are not at this time making MMC cards that will work with the PowerShot G10. Consequently, they are very hard to come across used and unaffordable.


The best SD memory card for the Canon PowerShot G10 is the SanDisk Extreme Pro 32GB SD Memory Card. However, the Lexar Professional 32GB SD Memory Card offers the best value.
