Best PowerShot D20 SD Memory Card

´╗┐The Canon PowerShot D20 may use SDXC, SDHC, and SD memory cards. A card with fast write speeds is important for video and burst shooting.

The card you purchase is a big influence on the performance of your camera.

If you are in a rush, here’s the best memory card you can buy for the Canon PowerShot D20:

  • UHS-I, U1, and Class 10 Speed Rating. Can sustain 10MB/s write speeds.
  • Excellent choice for photos.
  • Capable of recording Full HD (1920x1080) Video.
  • Inexpensive with more than good enough performance.
  • Larger capacities are available for a reasonable price.

Best SD Cards

Like all things tech, the cost of SD cards has greatly fallen since the release of the Canon PowerShot D20.

Seeing as how inexpensive prices are, it doesn’t be intelligent to purchase anything other than a professional-level memory card.

SanDisk Extreme Pro, Lexar Professional, and PNY Elite Performance cards have excellent overall performance and dependability. I have never had corrupted data or a card become inoperable with those cards.

Every single issue I have encountered has been due to no-name unbranded memory cards. Hoping to save a small amount of money isn’t worthwhile if your PowerShot D20 will not function in the right way.

If you want to reduce your cost, select a smaller storage capacity SD card from a high-quality manufacturer. That way, you will not have to fret about the photographs stored on the card.

Speed, Class, & UHS Ratings

Card Speed

Speed ratings of an SD card is determined by the continuous write and read speeds of the card. SD memory card file write speed is critical for video as well as continuous shooting.

Slows SD cards can cut down the number of continuous photos the Canon PowerShot D20 can take. This is because the camera’s buffer will not be able to write to the memory card fast enough.

When recording video, a slow memory card can cause recording to stop. The video file could also end up being corrupted. If you are going to shoot video, it is critical the card you use meets the required continuous write speed for video.

Read speed is important for transferring files to a computer. If you are filling up cards with images or video, a card with a fast transfer speed will reduce the amount of time it takes the transfer to complete.

Speed Class Rating

/best-canon-powershot-d20-memory-card/sd-card-speed-class.jpg
SD Card Speed Class

A memory card receives a Class rating according to its sustained write speed. Cards that have a write speed of 10MB/s will be rated Class 10.

  • Class 2 - 2MB/s
  • Class 4 - 4MB/s
  • Class 6 - 6MB/s
  • Class 8 - 8MB/s
  • Class 10 - 10MB/s or faster

Every brand of card that you can buy will be rated Class 10. To check the class rating of a SD card, find a number inside of the C on the label.

Ultra High Speed (UHS)

/best-canon-powershot-d20-memory-card/sd-memory-card-uhs-i-rating.jpg
Example of UHS Rating

The Ultra High Speed (UHS) bus is available in SDHC, SDXC, and SDUC memory cards. The UHS bus memory cards to achieve faster read and write speeds.

Three different specs exist. They are UHS-I, UHS-II, and UHS-III.

You can find the UHS rating of a memory card by reading the front of the memory card. A Roman numeral I, II, or III on the front of the SD card, that will be the UHS rating of your card.

  • UHS-I - Maximum transfer rate of 104 MB/s
  • UHS-II - Maximum transfer rate of 312 MB/s
  • UHS-III - Maximum transfer rate of 624 MB/s
