Review on 📸 Carte Komputerbay 64GB Professional Compact Flash CF 1066X: Boost Your Photography Workflow with Lightning-Fast 155MB/s Read & 160MB/s Extreme Speeds UDMA 7 RAW Support by Kipp Amundson

writes like a BEAST. Other reviews relate (probably) to technical specifications. All I can really say is that it runs on my 7D at 1728W 16:9 Magic Lantern 14-bit RAW for at least 4 minutes. This is the longest continuous RAW video I've ever recorded. Update: I stopped using the card for about 4 weeks then plugged the card back in and took 1 shot. After 3 hours I tried turning the camera back on but the 7D couldn't read the card. The same with a Windows PC. 3 formats from different locations didn't work.
