even better than BBU cache is the newer 'flash backed caches'. works
the same, but uses a supercap rather than a battery, and backs the cache
up in a flashchip. typically 1GB cache on the newer SAS2 stuff. This
way you don't need to replace the batteries in 3 years or whatever, or
the complexities of having to move the raid card with the attached
battery if the mainboard or chassis failed.
