    These are desktop drives in a server setting, failure rates might not transfer over to enterprise drives in a server setting.

    Also, they're continuing to use Seagate drives, so I don't really know what their point is. If Seagate drives are so bad, why save $10 per drive and invest hours of tech. time into failed HDDs, RMAs, et cetera.

    Those are consumer drivers, I wonder if there's anyone doing similar study but purely on enterprise drives.

    If you look around the forum, it really does come down to luck. You'll see one guy say they had high failures from brand A, but brand B is doing really well. They'll get a reply back that brand B isn't so good, brand C is better. Et cetera. I think, typically, WDs and Seagates are regarded as the most reliable on WHT.

    We'd concur with backblaze, we've had the most problems with Seagate - so much so we don't buy them any more unless it's Cheetahs. We've found Hitachi to be the most reliable as well, with WD somewhere in the middle if you discount the Raptors.

    I would be interested to know what types of chassis they use with these drives and whether the chassis is designed to insulate the drives from vibration issues. Some cheap chassis vibrate the drives to death.

    They discuss their chassis at http://blog.backblaze.com/2013/02/20...orage-pod-3-0/

    their practice and finding proved the point that desktop-grade consumer drives shouldn't be installed in regular rackmountable chassis which won't have these external anti-vibration features.

    so, their take of enterprise v desktop drive is really not quite relevant to "regular" production environment in data center where offers no external "anti-vibration" mechanism at all, therefore users would have to rely on the internal anti-vibration design built onto those "enterprise" drives.

    I wonder what the number (defect rate) would be about all those desktop drives if BackBlaze removed all the external anti-vibration thingy from their pods?!

    What are their anti-vibration features?

    A big datacenter such as Softlayer might have some (internal) statistics on enterprise drives. Question is, how do you get it from them
