The Class speed rating of an SD memory card is dependant on the sustained write speed of the SD card. A Class speed rating of 2 means that the SD card can sustain a write speed of more than 2MB per second.

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

The highest rating a card can get is Class 10. There are SD memory cards that are considerably faster than 10MB/s. Those memory cards use other technology, such as UHS (Ultra Highspeed Bus), which use different rating criteria.

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.
