This debunking article, is, well, bunk.
The truth is 30 odd percent of Seagate 3tb drives failed in the first year. Pod version, pod type, pod size, usage, and internal vs shucked were all irrelevant. In fact, the external drives shucked failed less often than the internals even though they were exactly the same model. No other drive, bought at the same time and used in exactly the same way(s) had a failure rate like that. For example, the Seagate 4TB drives have one of the lowest failure rates, in exactly the same conditions as the 3TB model.
