How to use

Insert a compatible SD card into the reader's SD slot until it clicks into place, then connect the reader to a computer's USB Type-A port. The operating system should recognize the reader as a removable drive; open the drive to copy or move files. For optimal transfer speeds, use a UHS-I SD card rated to support the higher read/write performance and ensure the computer port supports USB 3.x where possible.

Recommendations

Use high-performance SDXC UHS-I cards (such as SanDisk Extreme PRO) to achieve the stated maximum read/write speeds. Avoid forcing cards into the slot, and safely eject the reader from the computer before unplugging to prevent data corruption. Store the reader in a protective pouch when transporting it with camera gear.
