I have an inordinately high failure rate with WD Green in the 1 and 2
TB sizes. About 70% were replaced in their first year, about 50% have

I expect you are correct. Higher QA standards? Tighter
tolerances in the engineering? Using better specified parts at a
higher cost? Probably all of the above.
