A recent article in Server/Workstation Expert, entitled "NAS Wars," might be of interest here:

I applaud Alan's efforts at applying a bit of math and a lot of common sense to such a sticky issue.
This isn't meant to start a flame war, though something I read as a kid on a package of firecrackers comes to mind: "Light fuse, and run away fast!" ;)
Personally, I would suggest reading the first three sentences of the conclusion first, and with that perspective, read the rest of the article. Read that way, the methods and assumptions and calculations and configurations make for good detective work, IMHO.
Until next time...
