With XFS, it might, depending on how often the cache is flushed.

I don't really see that as a problem.  The disk heads must continuously seek 
to the next track anyway.  So what if they have to skip 2 or 3?  It's not 
going to be an issue.  The real problem is if it has to seek back and forth 
all over the disk.
