Sandisk Extreme Pro 300MB/s UHS-II Review

The Sandisk Extreme Pro UHS-II memory card is a top performer among UHS-II memory cards. There are two UHS-II memory cards by Sandisk, one that read and writes close to 300MB/s and one that is limited to 280MB/s. Of the two the 300MB/s card is superior, not just because it’s faster, but because it also performs really well in UHS-I devices.

You can see which is which by looking for the 300MB/s label on the card.

 

Sandisk Extreme Pro 300Mb/s UHS-II Memory Card Sizes

The Sandisk Extreme Pro UHS-II card is available in three sizes – 32GB, 64GB and 128GB.
