My internal card reader having slammed, yes it is possible !!!! I resolved to buy an external. More convenient because does not mount the letters constantly on the main PC and especially useful when traveling with the notebook. No need to connect the camera to the laptop and wait one hour for the 64GB card is empty along the battery from the camera. Now used at home or traveling the external card reader is convenient and fast. I do not penssait that the flow would spend the 20MB / s USB3 telling me that this was just marketing and that my card would not allow it. Finalament big surprise with transfer at 80MB / s. Very good purchase and perfectly satisfied.
