Best Canon PowerShot Digital Camera Memory Card

The Canon PowerShot A400 can use SD memory cards. The maximum capacity SD card that is compatible with the PowerShot A400 is 2GB.

SD memory cards labeled as SDUC, SDXC, or SDHC are not going to function properly in the PowerShot A400. These cards are easy to avoid as they are 4GB or larger in capacity.

If you are in a rush, here's the best memory card you can purchase for the Canon PowerShot A400:

Best SD Cards

Transcend and SanDisk both manufacture high-quality memory cards. Avoid ordering cards from low-priced third party brand names.

Memory card issues, for example, a complete loss of all of your photos as a consequence of data corruption is much more likely to happen with low-priced cards. The reduction in construction quality is not worth the tiny cost savings.

Buying a smaller capacity memory card is a smart way to save some money. They commonly are a tiny bit lower in price and you won't have to be concerned about the SD card having data failure.

Keep in mind, SD card issues are uncommon. Over the years, I have only had 2 cards fail on me. Age could have contributed to the failure, as the SD cards were bundled with previously owned DSLRs.

Canon PowerShot A400 SD Card Compatibility

4 separate specifications of Secure Digital (SD) memory cards are currently available. The Canon PowerShot A400 is limited to using SD memory cards. Each new memory card standard raises the maximum storage capacity and transfer speeds when compared with the earlier 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 PowerShot A400's card reader will only work with the first SD card spec. SDHC, SDXC, or SDUC memory card cards won't be compatible.

  • Secure Digital (SD) - These memory cards have a maximum capacity of 2GB and are compatible with the PowerShot A400.
  • 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.

Attempting to use a card that has a storage capacity of 4GB or larger in size in the PowerShot A400 will cause the digital camera to display an error.

Use a memory card that has a storage capacity of 2GB or less to prevent the problem.

If you attempting to use a memory card that has a storage capacity less than 2GB, and it is not working correctly, try to format the SD memory card in the camera.

Speed, Class, & Capacity

SD Card Image Capacity

The following is an estimation of the amount of large JPEGs you could expect to store on an SD memory card.

  • 512MB - 240 images
  • 1GB - 480 images
  • 2GB - 960 images

Memory Card Speed

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

SD Card Speed Class Rating

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 related to 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 minimum 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 an SD card can be given is Class 10. There are memory cards that are a lot faster than 10MB/s. Those SD memory cards use other technologies, such as UHS (Ultra Highspeed Bus), that have 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.

Conclusion

The best SD memory card for the Canon PowerShot A400 is the SanDisk 2GB Class 2 SD Memory Card. However, the Transcend 2GB SD Memory Card offers the best value.
