SD memory card (-2GB) / SDHC memory card (-32GB) / SDXC memory card (-512GB)UHS-I / UHS-II / Video Speed Class V90 This is from their website...But in general I think V60 or V90 cards work best with Video....

Yes, the UHS-I 95mb/s cards...So you're saying these are faster than the lexar 150mb/s UHS-II cards? My worry isn't the speed at this point - Its the fact that the Lexar cards failed and I could've been in a position where I lost data!

I bought a Lexar 1000x 64gb card for use with the X-T3... Everything worked fine until I came back from a shoot and plugged the card in through a reader - the computer asked to initialize the card! And then when I put it back into the camera, it said it needs to be formatted. I lost all the data on the card and had to reformat it - But formatting it via the computer didn't work (Disk Utility would keep freezing up) and formatting it via the camera resulted in the same issue if I tried to take a picture again. I was in touch with the folks at SDcard.org and I sent them the error their formatting software threw up - They say its quite likely that the card had a hardware defect. Fortunately the shop replaced the card. This time I also bought a slower Sandisk (95mb/s) card as a backup on slot 2. Just yesterday, I came back from a shoot and put the Lexar card in - The computer wouldn't recognise it. I tried another card reader - No luck. I put it back into the camera and it says 'Card Error'. So that's 2 Lexar cards! Luckily, the first shoot I was able to recreate at no extra cost and the for the second shoot I had a backup card. But this is extremely scary! Is there a possibility that the problem is with Slot 1 on the camera? How can I test this without frying another card? Or is it a combination of the X-T3 and the Lexar 1000x that's causing a problem? What do you all think?
