I missed it when I searched because I mis-scanned it as raidle instead of raid1e. RAID 1E would be less likely to be misinterpreted. So, it should have write performance somewhere between a pair of drives in RAID 1 and four drives in RAID 10, assuming the controller hadles it well. I'm still curious to see raw I/O numbers for random and sequential scan against the array. -Kevin -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
