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. :)
