Loss of completed/committed data is the problem.
The problem is not data loss, it is loss of data integrity. This is why we
have transactions in databases and filesystems: on a crash or loss of
power, we want transactions to be either completely lost or completely
saved, not in some in-between incomplete state.
There is no caching disk controller that knows how to ensure this.
