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.

    How can this be a review when you state specs from the box? Why not try to see what the write speeds are in real life bro.

      ATENTIE !! Vitezele in real-life sunt de genul 75 MB/s Read si 34-35 MB Write

    Thanks for your nice news! This mentioned
    Micro SDXC card seems to be really worth trying. Honestly, recently, I just searched
    much similar card news and wanted to choose a useful one for the camera of my
    boy friend. Hope this one is much efficient than the previous Micro SD


    Nice….! I remember when you had to practically sell a foot or an arm just to get more memory cards back in the day. Bought my wife a 7MP canon digital rebel XT when they first launched. A grand for the camera and I think I paid over a hundred dollars for a one gigabyte compact flash card!
