I have been buying WD Black drives. All other consumer drives have reduced their warranties, often to as little as two years (some were only a year for a while, but I think they're back to two). That suggests a lack of confidence in new materials and/or methods. I had one DOA drive, but that can happen to anyone; I've put 6-7 out there over the last few years, and none have so much as hiccuped.
Edit: To be fair, I've got some Seagate Barracudas out there too that have been flawless, but they are pre-flood 7200.12 models from before warranties dropped.
