I have to second the raid10 proponents. Excellent redundancy,
performance, and minimizes rebuild time--meaning you're back up to
full redundancy that much quicker after a failure. It also maximizes
the failure combinations you can withstand.

If you use the md raid10 driver, you can actually achieve near raid0
read performance (depending on layout choice and access pattern of
course). You can also use the md raid0 on top of raid1 components.
