Yes, but wouldn't you face exactly the same issues if you ran a UFS-like filesystem in asynchronous mode? Albeit it's not the default, but performance in synchronous mode is usually pretty poor. The fact that ext2 defaults to asynchronous mode and UFS (at least on the BSDs) defaults to synchronous mode seems like a total non-issue to me. Is there any more to the alleged difference in reliability?
