This card has worked perfectly with the Canon 1D X Mark II. I have used it for only 26 days so far, but it has not skipped a beat in that time. I have had both Lexar and San Disk cards lock up with the the Canon 1D X cameras (version I, and earlier on with version II). Problems seem to happen more often with new memory cards. Some of the new ones that had errors early started working perfectly later, perhaps due to firmware. However, this card, even though brand new, and faster than the other options, has proved to be utterly reliable so far. I don't even notice it, which is a good thing... although I absolutely do appreciate the amazing speed of the card when downloading photos to my Mac Pro Thunderbolt DAS.
Normally I wouldn't review a brand new card only 26 days after purchase unless it had failed on me, but I feel like this card is working so well that it deserves a review. Everything in my experience has proven that it is a winner and can be trusted as a worthy success to Lexar and SanDisk. Perhaps the future might even prove that it is superior to them both, who knows?
