I ordered one which came today. Given it claims to have been made in China and Samsung say they only make them in Korea or the Philippines it isn't going to be legitimate. The capacity is 64GB (strictly 60GB once 1Gb=1024Mb. The speed doesn't seem to be anywhere near the 60MB/s write and 100MB/s read, closer to 30MByte/s according to h2testw; though that could be down to local variables?
Mine arrived today, passed all the visual checks, H2testw results show full 64GB Will test in the GoPro later
Well the 64 gb card arrived and clicked on properties and its a working 64gb card. Formatted it and have it in my Nextbase InCarCam 512GW 6.8 MP Dashboard Camera and so far no probs. (y)
