Ot hard drive stress test

[Brian Cluff]

Unfortunately, I don't have any hard numbers, but my experience comes 
from the Desktop environment and the "server grade" drives seemed to do 
a little bit better than when I used consumer grade drives.  Perhaps 
that handle power cycling better.

I do wish I had kept really good notes though since I had at least 
10,000 drives go though my hands, and it would be interesting.
