I thought about doing this once on a Linux box. What I was thinking about was
creating a large RAM disk, and use that disk together with a physical drive in
a mirror setup. However, I was never able to create a large enough RAM disk back then
(must have been like LInux 2.0), and also the RAID mirror code wasn't able to
support such a mix of devices (i.e. RAM disk + physical disk). The situation might
have changed by now.
