Huh? I thought that "bitrot" was like content saved into the disk and the disk left unpowered for an extended period of time causing data loss. And I thought that the content stored on the disk has ECC on its own?

You get a corrupted bit in memory, you take and save that corrupted content to disk and no error correction on the disk level will help you.

I made the mistake of running a big PostgresSQL database on non-ECC memory once and I must say, it taught me some hard lessons.
