And I'm not actually wanting to use RAID 5; it's RAID 6 that I'm considering... You have 4 disk bays and you want RAID-6? How will that improve anything over RAID-10? You will have the same amount of available space, and the writes will be slower. Ok...there is *one* advantage: you can lose any two drives at the same time and still survive, with RAID-10 if you lose the wrong two drives you're hosed. That said, on one of my production DB's, I have a 16-bay raid enclosure and I run RAID-6 + hot spare. It even has an Areca controller made visible to the server as a single drive via fibre channel. Very sweet setup. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
