That's a one-eyed point of view. Ever taken a look at the failure rate of WD's green drives? Makes those Seagates look positively reliable in comparison.
The truth is that every drive manufacturer has had some lemons, but in every thread on this issue there is always at least one Seagate-basher. Please understand that WD have made some real stinkers in the past, and currently hold the crown for least reliable consumer grade HDD.
