All depends on the drive family.
I've stayed away from the entry level consumer drives (WD Blue, Barracuda) since both Seagete and Western digital would only warranty them for a year, which should tell you all you need to know about the quality and expected failure rate.
While the Seagate Constellation drives are just as good, but WD Black's are that little bit cheaper and easier to find.
