High Speed

There are two types of expressions in speed. One is the maximum transfer speed for devices, and the other is minimum speed for SD memory cards.

The variety of speeds allows developers to select just the right speed for the right device and allows you to find the memory card that meets your needs and your budget.

1. Maximum Speed

This means the maximum speed in which your device may write on, or read from, your SD memory card.

(Note: The average speed that your device writes to an SD memory card may vary depending upon the device and the operation it is performing. Your device may perform those functions at speeds less than the maximum speed. The speed may also depend how on other data is stored on the SD memory card.)

Higher speed products:

• Provide the speed needed for rapid shots that require less time between photos
• Transfer files faster from your SD memory card to your computer

Lower Speed
High Speed
Real-time Speed

Example: Consecutive shooting of high-resolution pictures

2. SD Speed Class (Guaranteed Minimum Speed)

SD Speed Class for UHS and non-UHS products is specified so that the minimum and constant speed is guaranteed for video recorders and digital cameras. Smooth performance is defined no matter what data (like music, video, photos) you are saving.
