Final Thoughts and Conclusion

If you have a need or desire to have one of the fastest microSDXC cards available, there are only a handful of choices.  The SD Association came up with the UHS-I Speed Class 3 rating to support 4K2K video recording, which requires a minimum of 30MB/s write speed.  Kingston has released their first card with the latest UHS-I Speed Class 3 rating, featuring read speeds up to 90MB/s and write speeds up to 80MB/s.

The Kingston SDCA3/64GB card surpassed the rated read speed of 90MB/s with a CrystalDiskMark score of 93.75MB/s, but fell just shy of the rated write speed of 80MB/s with a score of 74.57MB/s on the test system; it still exceeds the requirements of the Speed Class 3 rating.

The SDCA3 microSDXC card is available in three sizes, 16GB, 32GB and 64GB both with and without the adapter.  All of which includes a lifetime warranty if anything should happen to it.  The 64GB version that Legit Reviews took a look at can be found online for $53.72 with free shipping.

    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
    card: http://www.icare-recovery.com/howto/micro-sd-card.html

    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!
