Kingston U3 SD Memory Card Review

Kingston makes a few different cards with different speed classes. Most aren’t very popular except their U3 memory card, which is an incredible card that I always recommend as a great alternative to the Sandisk Extreme Pro Memory Card. 

In terms of in-camera UHS-I performance, the Kingston U3 card is almost always in second place, just below the Sandisk Extreme Pro by about one or two megabytes per second. Like Sandisk they also have a lifetime warranty. 

Kingston U3 UHS-I Memory Card Sizes

The Kingston U3 card can be found in four sizes – 32GB, 64GB, 128GB and 256GB.

Real World Memory Card Performance

Read and write speeds for the Kingston U3 cards are some of the best out there for UHS-I cards. Although the card is rated for 90MB/s read, and 80MB/s write, I get slightly faster results with USB 3.0 tests. In-camera results can usually get very close to maximizing the cameras potential, which you can see in the memory cards speeds of the Canon 6D II.
