How to use

Insert the Samsung T7 microSDXC card into the microSD slot of a compatible smartphone, tablet, action camera, drone or handheld console. For best performance, check that the host device supports UHS-I and the file system appropriate for the card capacity. Use the device settings to format the card if prompted before first use. To transfer files to a computer, use a compatible card reader or connect the host device directly and follow its file transfer procedure.

What to consider before purchase

• Confirm that your device supports microSDXC cards and the UHS-I interface
• Check device limits for maximum supported capacity
• Consider required sustained write speeds for your recording tasks (V30 for 4K video)
• Remember that actual transfer speeds depend on host device and interface

Recommendations

For reliable recording and transfer, format the card in the host device before first use, periodically back up important files to separate storage, and avoid removing the card during read/write operations. Use a UHS-I compatible reader or device to approach the stated read speeds and store the card in a protective case when not installed.
