Review on 📸 SanDisk Extreme 64GB microSD - SDSQXA2-064G-GN6MA: Enhance 4K UHD Performance with A1/A2 Capabilities by David Garnic

Unfortunately I had to listen to the negative reviews on this product. They either sent me a fake SanDisk or a card that doesn't exist. An advert for a 64GB card reads: "Read speed up to 100MB/s; Write speed up to 60MB/s. Actually, here are the tests (USB 3.1): WriteTest:QT 1:11.04QT 2:10.855QT 3:11.040QT 4:9.938ReadTest:QT 1:19.563QT 2:18.232QT 3:18.68 QT 4:18.232This card has been rated U3, which means the card supports a minimum sustained write speed of 30MB/s, making the card suitable for 4K video recording. However, this card fails miserably.
