When writing to an existing log file, random writes are used from size 0. Before writes hit the end of the file, the file size doesn't change, so the I/O for metadata might be avoided (also depends on file system mount options). Assuming most WAL files will have similar sizes, I/O needed for metadata will be minimal.
