Review on Amplim 64GB V90 UHS-II SD SDXC Card: Lightning Speed, 300MB/S, Secure Digital Memory Storage for Pro Photographer and Videographer by Marcos Oner

This card works with Panasonic Lumix GH5S at maximum UHD, ALL-I 400Mbps! Drive in a moving car for 45 minutes through a series of super detailed scenes. Recorded flawlessly. I'm impressed with the value for money. Before that I wanted to buy a Panasonic Micro P2 B v90 series. They're twice the price at $329 and only offer a meager 64GB. I can get 1 hour 24 minutes at ALL-I 400Mbps on 256GB. 64GB is not enough for UHD and ALL-I 400. I am buying 4 more of these 256GB Gold V60s for my GH5s and ALL-I 400 UHD recording to complement my Express P2 512GB for Varicam media. They cost about $1,800 each, but offer the highest level of security for data reliability. Despite being an older V60, the data transfer speed of the Panasonic AJ-MPD1G is quite fast. I get 290-320 MB/s persistence throughout the upload process. It's pretty fast. As fast as the Micro P2 A series.
