I've noticed that these are consumer-class drives, not server-class. I can't remember the last time WD was considered a reliable brand? Back when drives came with defect lists, perhaps. Cheap and cheerful has been WD's strategy, and while it's worked for them, it's also given them a black mark. You can get better from WD if you're willing to pay -- but who would? Given that, I'm not surprised WD bought Hitachi. They needed better drives and a better name, and HGST -- Hitachi -- has been excellent for a long time. Though they have their dark times too, remember the IBM Deathstar? (I'd almost forgotten they were responsible for that...)

That said -- drive reliability went down steadily once capacities exploded into the dozens then hundreds and thousands of gigabytes. The drive industry chopped their warranties from 3 to 1 years long ago to reflect this, they're inevitably more sensitive devices. The number of spare sectors a modern hard drive keeps -- the percentage of sectors which can die and not be considered a fault -- is disturbing.
