My nearly 4 year old Seagate Constellation ST3000NM0033 7200 RPM drive just failed, still within its 5 year warranty. I am requesting a warranty replacement, but does anyone have any opinion on the reliability of a refurbished Constellation drive versus a new Barracuda Pro? Would I be better off just buying a new Barracuda Pro and selling the refurbished Constellation that I get back from Seagate? Which of these is a better overall drive? If all things are even, I would obviously just wait for the refurb to arrive and use that, but if I can avoid problems down the road with a new Barracuda Pro, I may prefer to do that.
