RAID 5 typically does not equal the performance of RAID 0+1 because of the overhead required to calculate and write parity data. Write-intensive data files, redo logs, etc will perform better under RAID 0+1.

Agreed. RAID 5 is a good compromise in regards to providing redundancy for a reasonable cost, but it is not always the answer...
