-/// can only guarantee that the data is passed to the drive. It is up to the
-/// drive manufacturers to do the actual persistence properly, which they often
-/// don't (especially on consumer-grade hardware). Therefore, it is up to the
-/// user to validate their entire storage stack, to ensure the writes are
-/// persistent.
-/// Corollary: especially when dealing with larger amounts of money, it is best
-/// practice to have multiple channel data backups and not rely only on one
-/// FilesystemPersister.
