Different Classes Of A MicroSD Card

Not everybody fully understands the types or classes of a 
MicroSD card, and not every gadget out there is compatible with every class, so its also an important factor in buying a expansion card for your beloved gadget. there are a total of 4 classes of MicroSD cards which are the following. 

Class	Speed
Class 2	2 MB/s
Class 4	4 MB/s
Class 6	6 MB/s
Class 10	10 MB/s

as you can see the class of the card determines its speed in data handling, so in simple terms higher class means higher transfer speed, read and write speeds of your card, but it also affects the performance of your devices when it comes to installing or loading games and applications which are installed on your sd card. it also affects things like watching movies or taking videos and saving them directly to your sd card, so for photographers they usually go for higher capacity cards like 16 or 32gb and with a class of 6 or 10 would do. for smartphones i would suggest getting a class 6 card. and for everything else try class 2 or 4 but always check the compatibility of your device with these cards.  

so next time you buy on these cards, be sure to buy the class 
that fits your needs.
