Correlation does not always indicate causality though, of course. It's just the notion that a tool is required to be of a certain size to be professional that is amusing. I guess while Microsoft has been trying to catch up to this whole internet thing, that they got sidetracked and ended up adopting pornstar like philosophies.

But were not talking about causality, we're talking about a correlation . . . They're not saying that th tools are big because they are professional, they are saying that professional tools are big.

The study examined large production systems, including high-performance computing sites and Internet services sites running SCSI, FC and SATA drives. The data sheets for the drives indicated MTTF between 1 and 1.5 million hours. That should mean annual failure rates of 0.88%, annual replacement rates were between 2% and 4%. The study also shows no evidence that Fibre Channel drives are any more reliable than SATA drives."
