Make a single RAID 10. It´s simpler and it will provide you better write performance which is where your bottleneck will be. I think you should minimize the web server role in this equation as it should mostly work on cached data. -- Sent via pgsql-performance mailing list (pgsql-performance@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
