Using a SSD for the database storage should speed up the setup
considerably. In my experience, they feel a bit like a in-memory database
;-).
RAID0 for the spinning disks won't give much of a win, because database
stuff is normally more bound to seek performance, than to io bandwidth, and
only the latter will improve in that setup.
