Slashdot has a new article which says:

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.
