Designed for the fast ingestion of UHS-II SDXC media on systems that support 10 Gb/s USB 3.2 Gen 2, the Dual-Slot UHS-II SDXC USB-C 3.2 Gen 2 Card Reader from ProGrade Digital is equipped with a USB-C 3.2 Gen 2 interface and dual card slots, both of which support UHS-II SDXC media. This card reader delivers transfer speeds of up to 1.25 GB/s, allows for both card slots to be used simultaneously, and power is received through the USB bus, meaning that no external power sources are required. A magnetic base helps this card reader stay secure within your workspace. Included are a magnetic plate, a USB-C to USB-C cable, and a USB-C to USB-A cable.
Please note that this card reader supports Windows 10 and macOS 10.6 or later. To achieve full USB 3.2 Gen 2 transfer speeds, your USB host connection, cables, and device must all support USB 3.2 Gen 2, which is also known as USB 3.1 Gen 2 and USB 3.1. For systems that don't support USB 3.2 Gen 2, this card reader is backward compatible with USB 3.2 Gen 1, which is also known as USB 3.1 Gen 1 and USB 3.0.
