How to use

Connect the card reader to an available USB 3.0 port on your computer. Insert compatible memory cards (CF, SD or MicroSD) into the corresponding slots; the reader can access up to four cards simultaneously.

Safely eject each card or device from the OS before removing cards or unplugging the reader.

Usage recommendations

Use a USB 3.0 port to achieve the stated 5 Gbps speeds; transfer speeds will be lower on USB 2.0 ports. Keep the cable connection secure and avoid bending the cable sharply to prevent stress on the USB connector. For large transfers, use reliable backup software and verify completed file transfers before formatting or clearing the original cards.
