Everything You Know About Disks Is Wrong

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."

Dr. Schroeder is pretty hot, too!

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. :)

seems like she could make her own job...

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.

I suppose dupes are good!

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.
