[Mp.blogs.com] *michael parekh on IT*: Technology: Unintended Consequences: The problem comes when you start to think about power consumption.It's not that disk drives consume so much power or that they haven'tcome down in consumption over the years, but each of those cabinetswill require using modern drives about 3,300 watts to run while thefull 100 petabytes will require 2.148 MEGAwatts. And all that heat hasto go somewhere, so the building will typically use three to four timesas much power for air conditioning as it does to run the drives, takingour total power consumption up to just under 10 megawatts, which attypical U.S. industrial power rates will cost about $5 million per year.
