Kingston Class 10 UHS-I (U1) SDXC Ultimate 64GB Card & MobileLite G3 Card Reader Review


In testing with QuickBench 4.0, we benchmarked with both the Large File Test, as well as the Extended File Test.  In the first, QuickBench determines read and write speeds of files graduating from 2-10MB while in the second, the file sizes increase significantly from 20-100MB.

Here we see much the same with ZoneBench 2.0, where the different transfer speeds associated to file sizes are monitored:
