LinuxQuestions.org - confused over terminology of internal storage and SD card storage - howto encrypt the 128GB of internal storage

Hello,

I am confused with the hardware terminology involved in storage on a Android phone. I am not sure I will be using the correct terminology in this post.

I have a Samsung Galaxy S10+ with 128GB of storage and 8GB of RAM. I did not add any removable SD card to the smartphone.

I checked the smartphone and the hardware used to hold the 128GB of storage does not appear to be a SD card. The smartphone indicated there is no SD card;

Code:

Settings->biometrics and security->Encrypt or decrypt SD card-> No SD card inserted

It appears I can easily encrypt a removable SD card. But, how do I encrypt the 128GB of internal storage?

What do I call the 128GB of storage? Is it a solid state drive? Is it simply referred to as internal storage? Is it an embedded SD card? I haven't even added a removable SD card.

I would like to encrypt the Android smartphone. But, the only option I can find is to encrypt a removable SD card.

How would I encrypt the hardware storing the 128GB of data?

What is the hardware used to hold the 128GB of storage?

Thank you.
