Review on Sony M Series SDXC UHS-II Card 128GB V60 CL10 U3 Max Speed 277MB/S Write 150MB/S Black (SF-M128/T2) by Chad Mills

I used this card once. It worked once. I have just used it for the second time in 6 months and it has completely failed. I used it in my Sony A6300 and recorded around 20GB of 4K video. It looked good. After I turned the camera back on, the message "Cannot access memory card" appeared on my camera screen. I tried the map on my computer - no access. No recovery software can access it. I've tested many other SD cards in my camera and shot the same footage - they all work fine, no issues. If you care about your employees and can't afford to lose them, pay for the best card. Now I understand that this is the cheapest 100Mbit writing card because it's crap.
