RAID-1 or RAID-10 are the default, mostly safe choices. For disposable dbs, RAID-0 is fine. For very large dbs with very little writing and mostly reading and on a budget, RAID-6 is ok. In most instances I never recommend RAID-5 anymore. -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
