Best SD Cards
Make sure to buy a card from a company with a rock-solid reputation, such as Transcend or SanDisk. Inexpensive third party brands should be avoided.
Cut-rate cards are more likely to encounter data corruption, meaning you can lose all of your shots saved on the card. The decrease in quality is not worth the slight savings.
Buying a smaller sized capacity memory card is a smart and practical way to save a little bit of money. They commonly are a tad lower in cost and you won’t need to stress out about the SD card failing.
Keep in mind, SD card issues are very uncommon. Over the years, I have only had a couple of cards fail. Both of the memory cards were previously owned house cards that were included with the purchase of previously owned digital point & shoots.
Canon A620 SD Card Compatibility
Currently, four different specs of Secure Digital (SD) memory cards exist. The Canon A620 is limited to using SD memory cards. The benefit is that there is an improvement in the maximum storage capacity and read/write speeds with the release of every new 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 A620 will only work with the very first SD card standard. SDUC, SDXC, or SDHC memory card cards are not going to operate correctly.

Attempting to use a card that has a storage capacity of 4GB or larger in size in the A620 will cause the digital camera to display an error message.
Get a memory card that has a capacity of 2GB or less to prevent the error.
If you have a memory card that has a capacity less than 2GB, and the card is not functioning correctly, format the SD card while it is in the camera.

Memory Card Speed
Speed ratings for SD cards are determined by the 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
The Class speed rating of an SD memory card is based on the sustained write speed of the memory 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 memory card can get is Class 10. There are cards that are significantly faster than 10MB/s. Those memory cards use other technology, such as UHS (Ultra Highspeed Bus), which have a separate 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.
