If you use RAID, you have no control over data placement within the "slice" and there is definitely a performance hit with RAID-5. So, if you want optimum tuning capability, you should work at the individual disk level and mirror either at the Informix or the hardware level. Above a certain point, however, it becomes difficult to cost-justify carrying twice as much disk as you actually need.... :-) HTH. -- Ciao, Billy /Group Managing Director, The West Solutions Group: http://www.west.co.za \\ Drivel @ http://www.west.co.za/tasteless/ / \\ "Granted, Mr Wheeler's ideas are stupid and unreasonable, but he does own the company and I / think we should go along with him..." \\________________________________________________________________________________________________
