I read some negative reviews but decided to take the risk and buy this 256GB SD card. The negative reviews are correct. According to the description on Revain, it is a V90 UHS-II SD card. It is not true. Although the card itself has a label stating V90 UHS-II and a 299MB write speed, it does have a single row of pins on the back (meaning it's definitely not UHS-II). I'm seeing an actual write speed of around 10MB. I would give zero stars if I could. Such products should be banned by Revain.
