Putting the WAL on a second controller does help, if you're write-heavy. I tried separating indexes and data once on one server and didn't really notice that it helped much. Managing the space was problematic. I would suggest putting those together on a single RAID-10 of all the 300GB drives (minus a spare). It will probably outperform separate arrays most of the time, and be much easier to manage. -- A hybrid Escalade is missing the point much in the same way that having a diet soda with your extra large pepperoni pizza is missing the point.
