You so much as blink at these cards and they mysteriously stop booting, my 4K-capable A7R IV tops out at 100 Mbit/sec write rate for video, that's almost 24 hours worth on a 1TB card. Given the technical limitations of these devices, already storing that much footage on a card that is so slow to backup and with such limited rewrite lifetime seems insane. I love the idea of 2TB in such a tiny package, but the reality of who would actually buy these in large numbers and for what does not quite seem to line up with the tech.
