Everything You Know About Disks Is Wrong

Posted by kdawson on from the mean-time dept.

modapi writes "Google's wasn't the best storage paper at FAST '07. Another, more provocative paper looking at real-world results from 100,000 disk drives got the 'Best Paper' award. Bianca Schroeder, of CMU's Parallel Data Lab, submitted Disk failures in the real world: What does an MTTF of 1,000,000 hours mean to you? The paper crushes a number of (what we now know to be) myths about disks such as vendor MTBF validity, 'consumer' vs. 'enterprise' drive reliability (spoiler: no difference), and RAID 5 assumptions. StorageMojo has a good summary of the paper's key points."

    I would love to give her my very large hard drive. For "performance evaluation and measurement", you understand. ;-P

      Except she requires a MTBF of more than 3 seconds. Sorry dude.
      You call that failure?!? I'd call it success.

      MTBF, in this case, means Mean Time Between Farkings. So yeah, three seconds is an astoundingly short refractive period. :)

      This isn't Fark, it's Slashdot.

      You can say "fuck" here.

      Of course, that doesn't make this thread any more or less generally sexist, but hey, at least "fuck" is ok.

  2. seems like she could make her own job... by Anonymous Coward · · Score: 0, Offtopic

    as head of an independent testing lab. That would probably be a heckuva lot more interesting, and lucrative, than some random gig with Google, IBM, or MS Research.

    In fact the replacement rate was increased to every 2 years not for failure prevention but for capacity increases.

    I thought cable TV was getting way too many commercials.. How about increasing the programming instead. Disclaimer.. No longer a pay TV consumer.
