I know Henry. He's an enterprise storage guy. My guess is that he was coming from the perspective of enterprise storage builders. Which is to say, the Backblaze data may be a fine review of the experience consumers are likely to have with hard drives, it's a terrible review of what enterprise storage platform makers would do and what their buyers would expect. Whether or not that's an appropriate response to Backblaze, who intentionally and haphazardly uses consumer drives in their systems, is its own question. But what is certainly true is that you won't experience these kinds of failures from Tier 1 storage manufacturers (e.g., IBM, NetApp, EMC, Hitatchi Data Systems, et al). So in that particularly biased way, the study is indeed "deeply flawed".
