What Is The Difference Between A Class 10 microSD Card & A Class 4 microSD Card For Your HTC Smartphone

A few people have been asking me what that little number represents on their microSD cards that has a circle around it. That little number represents which class your microSD card is.
It is fairly simple. Most people have a microSD card that is a class four, which is the normal class, but what people do not know is that they higher the class the faster the memory will be accessible in your smartphone. I will tell you that reports are coming in that some class 10 microSD cards are freezing up smartphones but I also think that has to do with how strong your smartphone is.
Lets take the HTC EVO 4G LTE that will be released by Sprint in May. It will have a Snapdragon S4 1.5GHz dual core beast of a processor with 1GB of RAM and will be able to handle a class 10, 32GB microSD card with no problem.
All new smartphones that are coming out with at least dual core and 1GB of RAM can handle the class 10 but anything less you are risking some kind of crash of force close issue. Except for the HTC One line smartphones that will have no microSD slot.
Another helpful bit of information is be careful of your online purchases and make sure you are getting your microSD cards from reputable companies, because there a lot of fakes that will not work correctly. If you buy from eBay then make sure it is from a top rated seller.
In the end that little number with the circle means that the higher it is the faster it is.
