Best Canon PowerShot A430 SD Memory Cards

The Canon A430 uses SD memory cards. The largest capacity SD card that can be used in the A430 is 2GB. MultiMediaCards (MMC) can also be used.
SD memory cards described as SDUC, SDXC, or SDHC are not going to function in the A430. These cards are easy to avoid as they are 4GB or larger in capacity.

Best SD Cards
Make sure to select a card from a company with a good reputation, particularly Transcend or SanDisk. Low-priced no-name brand names should be avoided.
Bargain-priced cards are much more likely to encounter file corruption, meaning that you’ll lose all of your photographs on the card. The reduction in construction quality is not worth the minimal amount of cost savings.
In the event that you would like to save money, purchase a memory card with a smaller sized capacity. They should be a little bit less expensive and you will not have to be worried about the SD card becoming corrupted.
Always bear in mind, SD card issues are unlikely to occur. Through the years, I have only experienced a couple of cards fail on me. Age could have contributed to the failure, as the SD cards were included with pre-owned digital point & shoots.
Canon A430 SD Card Compatibility
The Canon A430 is limited to only using SD memory cards. There are currently 4 separate specs of Secure Digital (SD) memory cards. Each new memory card spec boosts the max storage capacity and transfer rates when compared with the prior 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 A430’s card reader will only work with the initial SD card technical spec. SDUC, SDXC, or SDHC memory card cards are not going to be compatible.
- Secure Digital (SD) - These memory cards have a maximum capacity of 2GB and are compatible with the A430.
- Secure Digital High Capacity (SDHC) - The capacity of these memory cards range from 4GB to 32GB.
- 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 A430 Memory Card Full Error

Trying to use a SD memory card that is 4GB or larger in size in the A430 results in the digital camera to show an error.
Use a memory card that has a storage capacity of 2GB or less to rectify the error.
If you are using a SD memory card that has a capacity less than 2GB, and it is not working, try to format the SD memory card while it is in the camera.
Speed, Class, & Capacity
SD Card Image Capacity
Here is a quick estimate of the amount of large JPEGs you can expect to store on an SD card.
- 512MB - 240 images
- 1GB - 480 images
- 2GB - 960 images
Memory Card Speed
Speed ratings for SD memory cards are established by sequential read and write speeds. The speed of the card is important in cases where many pictures need to be written or read from the card.
SD Card Speed Class Rating

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