A long time ago, for another application, we used to use battery
backed, write through RAM caches in front of real disks. The batteries
just had to last a few minutes, long enough to flush the cache onto
the disk. That would give you the best of both worlds, non-volitile
storage at RAM speeds; assuming such a device still exists.
