Don’t Buy The Sony Tough M Series SD Card

That’s a pretty strong statement and if you intend to use it in a UHS-I device then don’t do it.

The video explains all about it but the upshot is that it can’t keep up the speed required for video and even falls over on photos when you fragment the card. This all happens because it’s designed to read its optimum speed when using all the pins, which designed for UHS-II and unlike other cards which still work perfectly well on a UHS-I device – this one doesn’t 😞.

Have a watch of the video if you are still in two minds over it and I’ll also show you all the bench marking and tests done to confirm the result.
