Kingston 64GB UHS-I U3 microSDXC Review


Kingston UHS-I U3 microSDXC Card

4K2K video recording is getting more popular, as such we need faster media to record the higher resolution. Kingston works hard to keep up with the technology needs of today’s consumer. At CES 2015 they announced the microSD UHS-I Speed Class 3 card, capable of 90MB/s read, and 80MB/s write. The previous generation, UHS-I U3 was rated for 30MB/s read/write.


This new microSD card will be available in three storage sizes, 16GB, 32GB and 64GB. In addition, it will be offered in two different packs, one with a microSD to SD adapter, and one without. Kingston provided the 64GB version with the included adapter, part number SDCA3/64GB, which can be found online for $53.72 with free shipping.


As the popularity of high speed rugged cameras grows, the need for rugged storage devices is also growing. Kingston has listed that this little microSD card is water, shock, vibration, x-ray and temperature proof, and they back that up with a Lifetime warranty.


Of course to take advantage of these high speeds, not only do you need a camera that can use it, but you will also want to be able to transfer those pictures and video’s to a computer for editing and storage. Kingston recommends using their media readers such as the MobileLite Gen 3, MobileLite Gen 4 or their USB 3.0 Media reader.
