If you do use an SD card, use an official one rather than a random one. Not all SD card are the same and the official ones have been selected for this use.

This helps with wear and the power loss issue, which is the biggest issue with them.

When SD write, they shuffle which block is which to share out the writes. If power is lost in the middle of this shuffle, you get a new type of corruption no file system can handle. This is why you must shutdown anything running from an SD card, not just yank the power.

This is battle they can’t win and it just makes everything stupid trying.
