Review on 💽 SanDisk Extreme Pro SDXC UHS-II 64GB Flash Memory Card - Black, Gray, Red, White, Yellow by Adam Rogers

I used the card as a backup in a Sony A7R IV. My main card is the Sony Tough UHS II. The Sony card downloaded 100 files (25MB each) of compressed RAW images in two minutes. It took about 15 minutes for the SanDisk card to download 3 files of the same size, and I canceled the download at that point. I hope it's a defective card and I'll be happy with a replacement. Keep for updates.
