I agree having smaller regions would help the rebalencing situation both with rp and bop. However i an not sure if dividing tables across disk s will give any better performance. you will have more seeking spindles and can possibly sub divide token ranges into separate files. But fs cache will get shared across all disks so that is a wash.
