If you can fit 8 drives in it, for the love of god add two more and mirror your OS and xlog drives ( I assume that's what you mean by drive 2 for logs). Running a server on non-redundant drives is not the best way to do things. And if you can live on ~ 300 Gigs of storage instead of 450 Gigs, look into RAID-10 for your data array. RAID 10 is noticeably faster than RAID-5 for any database that sees a fair bit of writing activity. > It's overkill for our initial system but we are shooting for a system > that allows for growth.

And depending on your usage patterns 8 cores may well not be overkill too. ---------------------------(end of broadcast)--------------------------- TIP 3: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq
