How do you think standard SATA disks would perform in comparison to
this, and is a separate journaling device really necessary?

Perhaps three servers, each with 12 x 1TB SATA disks configured in
RAID10, an osd on each server and three separate mon servers.

Would this be suitable for the storage backend for a small OpenStack
cloud, performance wise, for instance?
