Wrong yet again. I made no such claim.

So we agree that you can't based on the Backblaze study claim that Hitachi drives in general are any more reliable than Seagate or WD drives.

RAID protection is only for failed drives. That's it. It's no replacement for a proper backup.

You really need to read more carefully (or possibly think more clearly, or both).

I'll tell you what...

I'm just going to keep talking about the Backblaze study. That real, actual thing, that happened, and was recorded, and published. You can keep ranting about probability and statistics (and keep complaining because when you steer the conversation away from the study and towards the abstract, people want expect you to back up what you say) To be very clear... you're the one who doesn't seem to want to talk about the backblaze study. You're the one who wants to keep this limited to a discussion of general probability and statistics, and you're the one who is complaining because people are asking you about the very topic you insist on steering the discussion towards.

If want to actually make a claim about this study then I'm all ears. If you're just going to keep trying to derail the conversation into a lecture about prob and stat, and then refuse to actually give said lecture I have no more interest in trying to have a discussion with you.

I have no issue at all with someone claiming I'm wrong if they'll explain what exactly I'm wrong about, and why exactly I'm wrong. I love learning that I was wrong about things... it means I learned something new. You however haven't brought anything to the discussion except trolling and nitpicking. You've refused to actually engage in any meaningful dialogue, instead choosing to talk in circles. Welcome to my ignore list. Good night.

So despite your previous denial, you do feel entitled to having someone teach you basic probability and statistics. That is kind of pathetic. frown.gif

Thank you, although I believe this was more of what I meant http://www.youtube.com/watch?v=kQFKtI6gn9Y

So to summarize my thoughts on the Backblaze blog post.

The study covered more than 25,000 drives, including 15 different models from 3 different manufacturers. The study concluded that of the drives observed that Hitachis had the lowest AFR, followed by Western Digital, followed by Seagate. They made no claims about manufacturer reliability in general.

And that is all that the study concluded.That's it.

If someone wanted to try and derive any other conclusions regarding the study, they should share their numbers, and show their work. If they didn't actually perform any further analysis, beyond what Backblaze did, then they should be clear to point out what they are sharing is an educated guess, not anything of merit.
