There were shockingly few of the Arri approved cfast cards made. These have a special code or chip that allows them to be used in alexa mini and Amira. No other 512gb Cfasts will work. No joke. Arri went through rigorous standards and testing for these cards and other 512gb cards couldn’t make the cut so Arri created a failsafe that only these cards could be used. This card is well used but fully functional working great. I took a video of it getting loaded onto the mini. Recorded and formatted and recorded again. Hit me with any questions. It was used sporadically for the last year.
