Review on Sony High Performance CAT-G64 💾 64GB CFast G Series 2.0 Memory Card by Joel Norfork

I had no problems with the Sony CAT-G64 64GB card. You write and read quickly, I did not notice any deviations from the stated speeds indicated on the card. I have to admit that I tested the speed but never had any problems. While CAT memory cards are a bit cumbersome to use (compared to SD cards), the Sony CAT-G64 64GB is a great choice!
