The card performs excellently in the machine, but it requires a special card reader on the computer to deliver the promised speeds. Otherwise, when used with a common card reader, it provides much slower speeds, even compared to the cheapest SD cards on the market.

For my mirrorless camera, which is also Sony, this is the ideal card. It has a large capacity and at the same time, due to its recording speed, it supports recording 4K videos with the maximum bit-rate, meaning the highest quality it can give me. So far, I am satisfied.
