Sandisk Extreme Pro 300MB/s UHS-II Review

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.

Real World Memory Card Performance

The Sandisk Extreme Pro 300MB/s card has the best combined read and write speeds of any card out there. I’ve seen cards read faster like the Transcend UHS-II, but then it writes a bit slower. This makes the Sandisk Extreme Pro the all around best UHS-II memory card. In terms of in-camera memory card performance, it runs very well in most cameras, but in some cameras like the Sony A9, a couple cards like the Sony and Delkin cards perform a few MB/s faster.
