SD Card Format As Internal or External?

[khiremandar]

Hi,
I have Moto G5S Plus, which has usable storage as internal 45.34GB & SD Card 117GB.

I want to know as for SD Card formatting there are two options.
1. Format as internal
2. Format (it keeps as External)

Question:-
1. what is difference between them?
2. Which is Better option?
3. Pros & cons?

Thanks,

Always external, sd card is not robust enough to handle the read/write traffic as internal for a long time.
Never do it as internal if you don't want to experience corrupt data in the future, it is a ticking time bomb. Its only advantage is installing app in your sd card.

Yeah generally external, or portable is best option. Really almost never a need to go internal these days.
