Best Canon PowerShot Digital Camera Memory Card

The Canon PowerShot G9 requires SD memory cards. 32GB is the maximum capacity SD card that will work in the PowerShot G9. MMCplus and MultiMediaCard (MMC) can also be used.

SD memory cards described as SDXC or SDUC won't work in the PowerShot G9. These cards can be easily avoided as they are 64GB or larger in size.

Don't want to read the technical details? Here is my suggestion on the card to get for the Canon PowerShot G9:

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 G9 SD Cards

Here are a few options to choose from that will function correctly with the PowerShot G9. With any of the cards outlined below, you won't have to worry about poor performance or SD card data corruption.

SanDisk Extreme Pro UHS-I SDHC Memory Card

Best SD Cards

Reliable memory cards are manufacture by both SanDisk and Lexar. Avoid buying cards from inexpensive third-party brands.

Inexpensive cards are much more likely to experience data corruption, meaning you will lose all of your photographs contained on the card. An insignificant amount of decrease in cost is not worth the decline in quality.

In the event that you want to save a tiny bit of money, purchase a memory card with a smaller capacity. They will be a tiny bit less expensive and you won't have to worry about the SD card becoming corrupted.

Even then, SD card problems are rare. Only only two cards have become corrupted out of the loads I have acquired over many years. The two memory cards were previously owned no-name cards that were bundled with the purchase of pre-owned cameras.

Canon PowerShot G9 SD Card Compatibility

Currently, four separate specs of Secure Digital (SD) memory cards exist. The Canon PowerShot G9 uses SD memory cards. The benefit is that there is an improvement in the read/write speeds and max capacity with the release of each updated spec.

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.

For more storage, cameras like the Canon Rebel T3i can use larger capacity cards. There are also many top lenses for the Canon Rebel T3i.

The Canon PowerShot G9's card reader is only compatible with the first two SD card technical 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 G9.
  • Secure Digital High Capacity (SDHC) - The capacity of these memory cards range from 4GB to 32GB and are also compatible with the PowerShot G9.
  • 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 G9 Memory Card Full Error

Trying to use an SD memory card that has a capacity of 64GB or larger in size in the PowerShot G9 will cause the point and shoot camera to show an error message.

Get an SD card with a capacity of 32GB or smaller to avoid the error.

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

Speed, Class, & Capacity

SD Card Image Capacity

The following is a quick estimate of the total quantity of large JPEGs you can expect to fit on an SD memory card.

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

Memory Card Speed

The speed rating for SD memory cards is established by the sequential read and write speeds. The speed of the card is important in cases where many photographs need to be written to the 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 card is based on the sustained write speed of the card. A Class speed rating of 2 means that the SD memory card can sustain a write speed of a minimum of 2MB per second.

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

The top rating a card can be given is Class 10. There are cards that are a lot faster than 10MB/s. Those cards use other technologies, such as UHS (Ultra Highspeed Bus), that have a separate rating standard.

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 technical standard was unveiled by Siemens AG and SanDisk in 1997. MMC cards appear to be a slimmer SD memory card.

MMC memory cards that will be able to work in the Canon PowerShot G9 consist of the 1st two generations. Suitable memory cards will be branded as MMC or MMCplus. Later versions are not going to function correctly with the Canon PowerShot G9

I wouldn't recommend purchasing any MMC memory cards. There is no one that is at present making MMC cards that will work in the PowerShot G9. Hence, they are unaffordable as well as being tough to obtain used.

Conclusion

The best SD memory card for the Canon PowerShot G9 is the SanDisk Extreme Pro 32GB SD Memory Card. However, the Lexar Professional 32GB SD Memory Card offers the best value.
