I suggest:                                # provide crash safety by flushing disk writes
                                          # (Disabling this can lead to unrecoverable data
                                          # loss if the system crashes.)

+1 for the change. I suggest shortening it to just "disabling this can lead to unrecoverable data corruption" (I think corruption is better than loss, mainly because too many people equate loss with "i may loose my last 10 updates, and I'm fine with that).
