Hi. Could you advice me about the best file placement in my situation. I'm preparing to move 2 databases from old machine (sql2000) to new 2005. I have 3 physical RAIDs:  RAID1 - system  RAID10  RAID1 The best place for data files is of course . But how to separate logs and tempdb? First database is Scala financial system, ~6gb, second one is automotive system (customers, parts/vehicles sales and purchases), ~3gb. I'm not sure about the read/write ratio though.
