I think HDD reliability studies are interesting from an academic standpoint, but aren't particularly useful for making purchasing decisions.
While you can make some generalizations about various brands it doesn't men a particular model you're going to buy is actually going to be any more or less reliable because a brand fared well in a reliability study. Okay... so what if the exact model was included in the study, you might be asking. Then you run into the "certainty" paradox. By the time a particular model has been tested long enough to draw any reasonable conclusions, that also means it's been on the market long enough that the drive is nearing obsolescence due to newer bigger better faster, cheaper drives being introduced.
So studies like this are great for Monday Morning Quarterbacking ("See! I told you those Seagate drives were crap!") but they have very limited use for influencing purchasing decisions for me. To wit, I'm not interested in purchasing any of the drives in that study that have been been used long enough upon which to draw a conclusion. Those that I might be interested in purchasing down the road, haven't been studied long enough to draw any conclusions.
RAID protection is only for failed drives. That's it. It's no replacement for a proper backup.
