MicroSD Cards Explained | Beginners Guide

Let's take a closer look at MicroSD cards. I will explain the basics (all abbrevations and tech specs), next to that I will test nine cards

with the very same specs and find out which one works the fastest and best and finally I will give the MicroSD cards a hard time

by going for an extreme durability test. May the force be with the MicroSD cards.

All MicroSD cards are available on Amazon: click at "Buy MicroSD Card" or at the image to see the current pricing.
