Best SD Cards

SD memory cards have dropped in cost since the release of the Canon PowerShot SX40 HS.

Due to the price range being so affordable, it would not be wise to pay for anything besides a high-quality SD memory card.

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

Every last hassle I have encountered has been due to no-name unbranded SD cards. Hoping to save a buck is not worth the cost if your PowerShot SX40 HS will not work properly.

To save money, buy a lower capacity card from a high-quality supplier. Because of this, you’ll not have to be concerned about the shots stored on the memory card.

Speed, Class, & UHS Ratings

Card Speed

Speed ratings of an SD memory card is dependant on the sequential write and read transfer speeds. The continuous write speed of a memory card is important for clearing the buffer for continuous shooting in addition to recording video.

A slow card can reduce the number of continuous frames the Canon PowerShot SX40 HS can capture. This is due to the camera’s buffer not being able to write data to the card quickly enough.

With video, a slow memory card can cause a sudden end to shooting. The video file may also be corrupted. If you are going to shoot video, it is crucial the memory card you use meets the requirements of the PowerShot SX40 HS.

Card read speed is important for transferring files to a computer or laptop. If you are filling up cards with images or video, a card with a fast read speed will save you time.

Speed Class Rating

SD Card Speed Class

The sustained write speed of a memory card is the criteria for the Class rating. Memory cards that have a minimum write speed of at least 10MB/s will be labeled 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-name SD memory card that you can find for sale today will have a Class 10 rating. To locate the class rating of a memory card, try to find a number inside of the C on the front.

Ultra High Speed (UHS)

/best-canon-powershot-sx40-hs-memory-card/sd-memory-card-uhs-i-rating.jpg
Example of UHS Rating

The Ultra High Speed bus (UHS) is built into SDHC, SDXC, and SDUC cards. The UHS bus allows for increased data transfer rates.

There are 3 different versions. The versions are UHS-I, UHS-II, and UHS-III.

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