Which is what disk subsystems like those from EMC do for you. They've
got build-in battery backup that lets them guarantee (assuming the
hardware's working right) that in the case of a power outage, all blocks
the operating system thinks have been written will in actuality be written
before the disk subsystem powers itself down.
