I have personally ran tests for performance using clarion arrays with NCR hardware. I compared RAID 1 (mirroring) with RAID 5 (parity). It cost about 15-20% of performance on inserts, as was about the same on reads. Remember, using raid you'll hide the disks from the Informix Partiioning. PaddyDD >
