Hi Loic,

This thread has been evolving, but I'd like to push it back a bit. 
Earlier in the thread you pointed out the CERN study on silent data 
corruption:

http://fuji.web.cern.ch/fuji/talk/2007/kelemen-2007-C5-Silent_Corruptions.pdf

If you are not already doing this, would it be possible for you to run 
fsprobe(8) on your X4500 boxes to see if there are any silent data 
corruption issues there?  You have a large enough storage farm to gather 
meaningful statistics.

Cheers,
 	Bruce
