While buying a memory card for smartphone everyone will give very important to its features like compatibility, speed and so on. Based on this features customer will choose faster memory card. Here we mentioned, how to choose a memory card with some class. Let us discus them briefly:
While measuring the speed of a memory card you must find out to which Class this memory is belongs. Due to speed class, the phone will be able to read and write information from memory card in faster way. Some device are unable to work well with memory card Class. While buying a memory card, you can measure card by using 2 forms i.e. Speed Class” or “UHS Speed Class”.
Let us discuss about Speed Class Vs UHS Speed Class:
“Speed Class” and “UHS Speed Class” measure the minimum sustained transfer speeds in flash memory.
Speed Class will indicate how fast information and data can be constantly written to the memory card. The higher the Class, the faster the speed in which your device can save information to the card.
- Class 2 memory card is the slowest memory card and data is written to it at a minimum speed of 2 Megabytes per second
- Class 4 memory card is the second slowest Class of memory card and data is written to it at a minimum speed of 4 Megabytes per second
- Class 6 memory cards have a minimum write speed of 6 Megabytes per second
- In Speed Class rating system, Class 10 memory cards is the fastest memory cards, which have a minimum write speed of 10 Megabytes per second
UHS speed of memory card:
UHS Speed Class memory cards consist of the UHS Speed Class 1 (U1) and UHS Speed Class 3 (U3).
- UHS Speed Class 1 has a minimal write speed of 10 Megabytes per second
- UHS Speed Class 3 memory cards have a minimum write speed of 30 Megabytes per second
Why we requires UHS Speed Class or Speed Class:
Let us consider a video recorder for example. If you want memory card with a speed class of UHS Speed Class 1 (U1) or a Class 10 card in order to record 4K video or even full HD video (1080p).In such cases when you try to use a memory card with a lower speed class rating then it is unable to work.
Speed Class will help you to eliminate buffering or loading times when information is being written to the card.
