While on the subject, in a home scenario where one actually notices the electric bill personally, is it more economical to purchase a big expensive 1tb disk and save on electric to run it for five years or to purchase two cheap 1/2 TB disk and spend double on electric for them for 5 years? Has anyone calculated this?
