I am faced with a hardware choice for a postgres data warehouse (extremely high volume inserts..over 200 million records a day) with a total storage of either 12 x 600G disks (15K) (the new Dell Poweredge C server) or 24 x 600G (10K disks) ALL direct attached storage. I am leaning toward the 24 disks as I expect the higher number of disks to provide overall better performance under high loads Does anyone have any experience with a mixed 10K / 15K DAS storage that you can share.
