Best PowerShot G15 SD Memory Card

´╗┐The Canon PowerShot G15 may use SDXC, SDHC, and SD memory cards. A memory card with fast enough write speeds is critical for continuous shooting and video.

You can wreck the functionality of your camera by using the wrong card.

Just want a card that is compatible? Listed below is my recommendation on the memory card to use with your Canon PowerShot G15:

  • 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 price level of SD cards has greatly fallen since the release of the Canon PowerShot G15.

Since the cost are quite cheap, it does not make financial sense to buy anything besides a professional-quality SD card.

The best SD memory cards I use have been the SanDisk Extreme Pro, Lexar Professional, and PNY Elite Performance models. I have never encountered unusable data or a card become inoperable with those memory cards.

All the trouble I have experienced has been because of generic unbranded cards. Attempting to save around a dollar is not worth the cost if your PowerShot G15 is likely to experience issues.

If you want to reduce your cost, pick a smaller storage capacity SD memory card from a quality supplier. Because of this, you’ll know your shots are safe and sound on the SD card.

Canon PowerShot G15 SD Card Compatibility

The only memory cards compatible in the Canon PowerShot G15 are SD, SDHC, and SDXC. For best performance, ensure that your camera has the most up to date firmware.

The newest cards, SDUC (Secure Digital Ultra Capacity), aren’t going to be compatible with the PowerShot G15.

Four separate types of Secure Digital (SD) cards that you should pay attention to. They are split up by their capactiy.

  • SD (Secure Digital) - 128MB to 2GB.
  • SDHC (Secure Digital High Capacity) - 4GB to 32GB.
  • SDXC (Secure Digital eXtended Capacity) - 64GB to 2TB.
  • SDUC (Secure Digital Ultra Capacity) - 4TB to 128TB.

Listed below is an approximation of how many max-quality JPEGs pictures you can expect to be stored on a memory card:

  • 16GB - 4,640 images
  • 32GB - 9,280 images
  • 64GB - 18,560 images
  • 128GB - 37,120 images

Speed, Class, & UHS Ratings

Card Speed

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

A slow memory card can cause a reduction in the number of continuous frames the Canon PowerShot G15 can capture. This is because the camera’s buffer will not be able to write to the card fast enough.

With video, a slow SD card can cause a sudden end to the recording. The video file could also be corrupted. If you are going to shoot video, it is critical the SD card you use meets the required write speed for video.

Read speed is nice to have for transferring files to a computer. If you have cards that are full, a card with a fast read speed will decrease the transfer time.

Speed Class Rating

/best-canon-powershot-g15-memory-card/sd-card-speed-class.jpg
SD Card Speed Class

A card receives a Class rating based on its continuous write speed. SD cards that have a minimum write speed of at least 10MB/s are labeled as 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 name-brand memory card that you can find will have a Class 10 rating. You can determine the class rating of a SD card by looking for a number inside of the C on the label.

Ultra High Speed (UHS)

/best-canon-powershot-g15-memory-card/sd-memory-card-uhs-i-rating.jpg
Example of UHS Rating

The Ultra High Speed (UHS) bus can be gotten with SDHC, SDXC, and SDUC cards. The UHS bus allows offers a way to improve file transfer rates.

There are 3 separate specs. They are called UHS-I, UHS-II, and UHS-III.

To find the UHS rating of a SD card, look at the front of the card. If the card has UHS, a Roman numeral I, II, or III will be on the memory card label.

  • 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
