In the morning I was trying to purchase a microSD card for my new HTC Desire 816 and I came across various classes of microSD cards. I wasn’t aware of what these classes mean, so I did a little research.
It is not something very important although to you it might seem important if the speed of data transfer matters. Basically there are 5 classes of microSD cards, viz, Class 2, Class 4, Class 6, Class 8 and Class 10 – I wonder why all the classes have even numbers. This is a speed rating and nothing else. 2 means the data can be transferred between the card and the devise with which it is being used (the phone, the laptop or the computer) with a speed of 2 MB per second. Similarly, Class 4 means 4MBps, and so on.
