Best Canon PowerShot SD950 IS SD Memory Card

Best PowerShot SD950 IS SD Memory Card

The Canon SD950 IS requires SD memory cards. 32GB is the biggest capacity SD card that is compatible with the SD950 IS.

MultiMediaCards (MMC) and MMCplus cards can also be used in the camera. However, they are not produced anymore. If you have one, you can use it. If you don’t have one, don’t buy one, they will be more expensive than an SD card.

SD memory cards described as SDXC or SDUC are not going to function correctly in the SD950 IS. These cards can be easily avoided as they are 64GB or larger in capacity.

The SDHC format was announced in 2006. All 32GB cards that are currently being produced will have almost identical performance. You cannot go wrong buying the cheapest class 10 name brand card. At the time of writing this, the PNY Elite 32GB SD memory card has the best price.

Here are a few options to pick from that are compatible in the SD950 IS. With any of the cards outlined below, you won’t have to stress out over card data corruption or poor capabilities.

Best SD Cards

Lexar, PNY, Samsung, and SanDisk both make reliable memory cards. Low-cost house brands should be avoided.

Cheap cards are more inclined to experience file corruption, meaning that you will lose all of your photographs on the card. A minuscule amount of decrease in cost is not worth the reduction in build quality.

Buying a smaller sized capacity card is a shrewd way to save a bit of money. They tend to be slightly less expensive and you won’t need to be concerned about the SD card having data failure.

Understand that, SD card problems are infrequent. Only a couple cards have become unusable out of the various I have owned over time. Both of the memory cards were used no-name cards that were bundled with the purchase of used digital cameras.

Canon SD950 IS SD Card Compatibility

The Canon SD950 IS is only capable of using SD memory cards. There are currently 4 different technical specs of Secure Digital (SD) memory cards. Every updated memory card technical spec raises the max storage capacity and transfer speeds when compared with the previous 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.

The Canon SD950 IS’s card reader will only work with the original two SD card technical specs. SDUC or SDXC cards are not going to work.

  • Secure Digital (SD) - These memory cards have a maximum capacity of 2GB and are compatible with the SD950 IS.
  • Secure Digital High Capacity (SDHC) - The capacity of these memory cards range from 4GB to 32GB and are also compatible with the SD950 IS.
  • 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 SD950 IS Memory Card Full Error

SD Card Contacts

Trying to use an SD card that has a storage capacity of 64GB or larger in the SD950 IS will result in the point and shoot camera to display an error.

Get an SD memory card that has a storage capacity of 32GB or less to prevent the problem.

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

Speed, Class, & Capacity

SD Card Image Capacity

The following is a quick estimation of the total quantity of large JPEGs you will be able to fit on an SD card.

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

Memory Card Speed

Speed ratings for SD memory cards are determined by sequential read and write speeds. The speed of the SD card is important in the event that many pictures need to be written or read from the SD memory card.

SD Card Speed Class Rating

SD Card Speed Class

The Class speed rating of an SD card is related to the sustained write speed of the SD card. A Class speed rating of 2 means that the SD 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 maximum rating an SD card can receive is Class 10. There are SD memory cards that are substantially faster than 10MB/s. Those cards use other technologies, such as UHS (Ultra Highspeed Bus), which use a separate rating standards.

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

Siemens AG and SanDisk released the MultiMediaCard specification in 1997. MMC cards appear to be a slimmer SD card.

The first 2 generations of MMC memory cards are going to function in the Canon SD950 IS. That includes the first memory cards labled as MMC and the second generation MMCplus memory cards. Later generations will not work with the Canon SD950 IS

Avoid ordering an MMC memory card. Manufacturers are not presently manufacturing MMC cards compatible with the SD950 IS. For that reason, they are unaffordable and challenging to find used.


Buy an SD memory card for the Canon SD950 IS based on price. An expensive card isn’t going to improve performance. As long as it is a speed class 10 card, you will be fine. My recommendation is the PNY Elite 32GB SD memory card.
