SanDisk microSDHC 16GB for Samsung Galaxy Tab 3

SanDisk Ultra 16GB microSDHC

I have a Samsung Galaxy Tab 3 7″ for my kids. It is 8GB version. So I have to get some external storage.

Now it is SanDisk microSDHC 16GB

SanDisk microSDHC 16GB

Yes, it is sold in China, with Chinese package.

The details of specification:

  • 16GB
  • Class 10  UHS-1
  • 30MB/s (Read)
  • Good for Android system or other smartphone or tablet.


Here is a closer look of the card.

SanDisk Ultra 16GB microSDHC

Than I open the external storage slot cover on the left side of Samsung Galaxy Tab 3.


Then I insert this microSD into the external storage slot. Pushed it in to the end and put the cover back. Power on the device.


After that, go to the settings >> Storage and look at the information of storage.


It shows 14.83GB. The capacity is correct. The labeled 16GB is based on 1GB = 1,000,000,000B. Inside of  computer or Android system, 1GB = 1,024 x 1,024 x 1,024 = 1,073,741,924B

Do a simple calculation, the answer will be 16 x 1,000,000,000 / 1,073,741,924 = 14.90GB

There is also small portion of space is taken by system use. That’s why the system can only provide 14.83GB for user use.
