Right. However, if the data is corrupted while in memory (e.g. on a PC with non-parity memory), there's nothing ZFS can do to detect that. I mean, not even theoretically. The best we could do would be to narrow the windows of vulnerability by recomputing the checksum every time we accessed an in-memory object, which would be terribly expensive.
