Very fast and high-quality finish memory card that does what is advertised and even more. Can only recommend this card. Had the 128GB SDXC Komputerbay Secure Digital Extended Capacity Speed Class 10 UHS-I 600X tasted as it was very cheap and had to realize that they can only write 30MByte / s. Not these the SanDisk business promised 60MByte / s and provides the read even 90MByte / s. Can only recommend it.
