Review on Amplim 64GB V60 UHS-II SD SDXC Card by Jim Velasco

This worked for me on my Panasonic Lumix GH5 at 4K 400 Mbs All-i 30fps 4:2:2 in v2.1 firmware . I burned the whole map, which took about 40 minutes today, 360 degree video. 128GB/128GB TF SDXC card. New November 2017 necessarily. With a smaller card from the same manufacturer, the card hung for 10-15 seconds. I don't know of any other card with zero crashes at maximum settings. Interestingly, this map was released by Amplin this month. Due to all the confusion about which cards work with the GH5 I just had to post my experience to try and help.
