Read / write test done on my computer (Mac) using the included USB 3.0 reader: - Reading: 90 MB / s - Write: 41 MB / s (See attached screen capture)
A detail: the "UHS Speed Class" noted on the card is type "U3" and not "U1" as currently shown in the photos on this page product. The packaging of the card that was delivered to me is exactly that of the 2nd picture attached below.
