FAQ
SD card labels identify the card standard, bus interface and speed classifications. Common markings include SDHC, SDXC, UHS-I and UHS-II, along with Class, U and V symbols. Your device manual can help you match these markings to its supported card specifications.
UHS-I and UHS-II are bus interface standards used for communication between a card and a device. UHS-II cards have an additional row of contacts. They can generally operate in compatible UHS-I devices using the UHS-I interface.
Check your device manufacturer’s specifications for supported SD card standards, bus interfaces and speed classes. Compare those requirements with the card’s listed specifications. Cameras, computers and other devices may support different combinations of these standards.
A computer with a compatible built-in SD card slot does not require a separate reader. If there is no suitable slot, an external card reader connects through a port such as USB-A or USB-C. Some cameras also allow file transfers through a direct USB connection.
SDHC cards typically use FAT32, while SDXC cards typically use exFAT. The file system determines how files are organised on the card. Support varies by device and operating system, so consult your device documentation for its formatting requirements.
