This is the reason I am biased towards ZFS and away from hardware -- I
would rather rely on a process of updating blocks to provide redundancy
than some chemicals "storing" some electrons.  Given high write throughput
environments can and often do require battery-backed write-cache, I will
do what I can to avoid such configurations.
