I was making a comparison between, "few, expensive, components
specialized for speed and reliability," and "lots of cheap components."
Whether it's Google Filesystem vs. an EMC system or a couple of
different ways of putting together a $3000 RAID system, the principles
and method of analysis are the same.

But for this particular case, someone appeared to be implying that
companies who have the money and need high reliability systems, such
as Akamai, go for specialized hardware. I was just pointing out that
that's not the case, and is certainly alone no argument for specialized
hardware.
