The DriverGenius UHS-II SD Card Reader (model U3CR08-DG) is a compact single-slot SD card reader that works with UHS-II, UHS-I and non-UHS Secure Digital cards.
The DriverGenius reader has a plastic body and includes a cover for the USB connector. The Type-A male USB connector is sits close to the body of the reader and may block adjacent USB ports. SD cards insert deep into the reader and in a somewhat counterintuitive fashion, the contacts of the SD card must face up, rather than label side up. The reader has a blue LED indicator light that is on steady when a card is present and blinks when the card is accessed.
