Brad, I think we have a responsibility to educate.

Like you, I was a bit unkind in my replies in this thread, because
the poster was using such great hardware with so little insight.

Turning this into a more constructive discussion: what about other
machine architectures (ignoring the Linux versus UNIX issue for now)?

What about other RAID levels? It seems to me that RAID 1 (mirroring)
would give at least the performance of a single disk. Any RAID
scheme that uses parity blocks will have slow random write performance
because of the unavoidable parity block read operations.
