Best Canon PowerShot SD990 IS SD Memory Card

Best PowerShot SD990 IS SD Memory Card

The Canon SD990 IS can use SD memory cards. 32GB is the biggest capacity SD card that can be used in the SD990 IS.

MultiMediaCards (MMC) and MMCplus cards can also be used in the camera. However, they are no longer manufactured. If you have one, you can use it. If you don’t have one, don’t buy one, they will cost more than an SD card.

SD memory cards that meets the SDXC or SDUC standards are not going to work properly in the SD990 IS. These cards can be easily avoided as they have a storage capacity of 64GB or larger.

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.

Below are some possibilities to pick from that will work correctly with the SD990 IS. With all of the cards outlined below, you won’t have to worry about SD card data corruption or sluggish overall performance.

Best SD Cards

Be sure to get a card from a manufacturer with a solid reputation, particularly SanDisk or Lexar. Avoid purchasing cards from inexpensive third party brand names.

Inexpensive cards are more likely to encounter file corruption, meaning that you can lose all of your images contained on the card. A small amount of decrease in cost is not worth the decrease of construction quality.

Buying a reduced capacity memory card is a savvy way to reduce costs. They should be a little bit more affordable and you won’t need to fret about the SD card losing your photos.

Bear in mind, SD card issues are very rare. Throughout the years, I have only suffered from only two cards fail on me. Both memory cards were previously owned no-name cards that were bundled with the purchase of previously owned digital cameras.

Canon SD990 IS SD Card Compatibility

four separate specs of Secure Digital (SD) cards are currently being manufactured. The Canon SD990 IS is limited to using SD memory cards. The benefit is that there is an increase in the transfer rates and max storage capacity with the introduction of every 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 card reader in the Canon SD990 IS will only work with the initial two SD card standards. SDUC or SDXC memory cards will not work.

  • Secure Digital (SD) - These memory cards have a maximum capacity of 2GB and are compatible with the SD990 IS.
  • Secure Digital High Capacity (SDHC) - The capacity of these memory cards range from 4GB to 32GB and are also compatible with the SD990 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 SD990 IS Memory Card Full Error

SD Card Contacts

Attempting to use a card that has a capacity of 64GB or larger in size in the SD990 IS will cause the digital camera to show an error message.

Get a card that has a storage capacity of 32GB or less to avoid the error.

If you attempting to use an SD memory card that is 32GB or smaller, and it is not working correctly, 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 how many large JPEGs you can expect to save on an SD card.

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

Memory Card Speed

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

SD Card Speed Class Rating

SD Card Speed Class

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

The MultiMediaCard standard was revealed by SanDisk and Siemens AG in 1997. MMC cards are similar in dimensions to an SD card, but they are a bit slimmer.

MMC cards that will be able to work in the Canon SD990 IS include the earliest two versions. That consists of the 1st cards labled as MMC and the 2nd gen MMCplus cards. Later generations won’t function correctly in the Canon SD990 IS

It is not a smart idea to buy any MMC memory cards. Manufacturers are not actively making MMC cards that will function in the SD990 IS. Thus, they are tough to obtain used as well as being very expensive.


Buy an SD memory card for the Canon SD990 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.
