jdlev - Good luck - your increase in performance comes with double the risk of total array failure. It's a balance of risk vs. performance....
Ain't that the truth! A good lesson is never trust the manufacturer's performance numbers. I forget what I read, but it was something like the expected life of the drives was like 2,000,000 hours or something ridiculous like that.
If I have to rebuild everything, you can bet your hind quarters I'll be doing a raid 1 config.
