**If you're unsure, ask for compatibility**


Devices like Actions Cams, Dash cams and Drones that are able to record in 4K quality or more need either a SanDisk Extreme or Extreme Pro card. SanDisk Ultra cards could be too slow for these devices.

If buying a 64GB or higher capacity card, make sure your device is compatible with exFAT filesystem, otherwise the card will become corrupted. If you are not sure about this please ask for advice.

All cards include a minimum 7-year manufacturer's warranty with the exception of SanDisk Ultra 32GB 100MB/s and SanDisk Ultra 64GB 100MB/s.

Cards may show less capacity than advertised. Read our disclaimer at the end of this description to know why this happens.

See how much you can store in a Memory Card:

Music    Audiobook        MPEG1 Video

What you get: X Size Pack of GENUINE Sandisk micro SD of your choice. (X meaning the pack quantity of your choice.)

One Gigabyte (1GB) means 10^9 = 1,000,000,000 bytes using powers of 10. A computer operating system, however, reports storage capacity using powers of 2 for the definition of 1GB= 2^30 = 1,073,741,824 bytes and therefore shows less storage capacity. Available storage capacity (including examples of various media files) will vary based on file size, formatting, settings, software and operating system and other factors.

Retail packaging design may vary from the one pictured.
