Source :

We are using external device here and  there nowadays, either for extending the storage for android smartphone device or to saving an important file.

Now, we are going to review in a bit for the Micro SD. Most of you already know what Micro SD is, so we won’t really explain it. To summarize it, micro SD is another extension of storage that can be added to your smartphone to make it won’t run out of storage. It could also be used to create a partition to made up for your small ram which is a problem for an old Smartphone.

Well, for the micro SD there is more outside the Storage which is in GB. There is usually 4,8,16,32 GB. Although the smaller one is rare this day. Beside the Storage  there is also the speed, which is symbolized in :


This symbol is in order from the smallest speed to the fastest speed. There are four different speed classes — 10, 6, 4, and 2. 10 is the fastest, while 2 is the slowest. Class 2 is suitable for standard definition video recording, while classes 4 and 6 are suitable for high-definition video recording. Class 10 is suitable for “full HD video recording” and “HD still consecutive recording.”

There are also two Ultra High Speed (UHS) speed classes, but they’re more expensive and are designed for professional use. UHS cards are designed for devices that support UHS. For smartphone devices, the class 6 is already enough for you, although it might causes a bit lag, it is still manageable.

As for the 2 and 4 class, it is not recommended  as the devices might heat up from overworking and might be a burden for the smartphone itself. If you want to be in the safe side, 6 is okay, and 10 is the best. Although there are two other, it is too much and is usually uses for professional things as stated above.

  • CLASS 2 – a guaranteed minimum write speed of 2MB/s or higher*
  • CLASS 4 – a guaranteed minimum write speed of 4MB/s or higher*
  • CLASS 6 – a guaranteed minimum write speed of 6MB/s or higher*
  • CLASS 10 – a guaranteed minimum write speed of 10MB/s or higher*

When buying an SD card, you’ll need to buy the right speed class, size, and capacity for your needs. Be sure to check what your device supports and consider what speed and capacity you’ll actually need. As stated, some might know this already, but some might not. Be sure to check it before buying as you might get swindled by the store and that is not a good thing.

Thank you for reading, and be sure to share article so that nobody get  swindled.
