I recently bought a Samsung Evo Plus 2017 to use it as Internal Storage on my phone, Moto G4 plus whose 32 GB is running out. After formatting as internal Storage, i was asked if i wanted to move my photos, files and some apps to this New SD Card which i accepted. Now my question is that suppose both the internal storage on my phone have some free space and i write or download something, where the data will be actually written? How would i know this? Is there any way i can control where i want my data to be written? The simple idea behind this is that i will put all the data that i don't wish to to modify or delete on the new Storage, and use Real Storage as the default, so the card doesn't degrade with consistent writes. Any help or suggestion will be appreciated.
