You're probably right on both counts.
I worry about what having one big pool would do to the likelihood of
losing all of the data on the box though; I think splitting it up gives
me a better chance of surviving multiple device failures, plus lower
impact if I'm wrong :)
I'll definitely try to find time to compare numbers though.
