In my experience, battery backed cache is always worth the money. Even if
you're mostly select, you will have some updates. And it'll also pick up
other write activity onthe system...
Of course. My point was that 64MB should be quite sufficient if most
accesses are reads. We have a few machines here with 2GB BBU caches as we
do LOTS of writes - that sort of thing probably isn't necessary here.
