Ext4 is prone to corruption as it doesn’t have much error detection. Whatever you do don’t lose power.
I use Ext4 since 20 years in all of my systems. And I had my fair share of power loses. It’s not a problem as you describe, because Ext4 is journaling. Ext4 is robust and one should not worry to lose data randomly.
A file system that contains its own recovery capability in the event of a failure. In a journaling file system, the information about the changes is recorded in a separate log (the journal) before the indexes to the files are updated. If a power or other system failure corrupts the indexes as they are being rewritten, the operating system can use the log to repair them when the computer is restarted.
