This is an interesting discussion and if anyone else has measurements or 
references that would help one choose among filesystems, it would be 
helpful to mention it here; there are obviously many 
choices--http://en.wikipedia.org/wiki/Comparison_of_file_systems--which 
may be more or less suited to one application or another.  We've ended 
up with jfs for our data warehousing for good reasons we think (files 
bigger than 2 TB, good write speed, no reliability problems that we've 
observed), but we certainly haven't exhaustively examined the alternatives.
