If you are on Windows I say definite YES!  NTFS still fragments.  I have 7 2-TB 
volumes, some DSSU, some hold Backup Exec images and some SQL dumps.  The 
fragmentation definetly hurts disk-to-tape performance on all those volumes.  
The BE images are the worst, causing 2+ million fragments within a month.  I 
see performance pick up by 30% by defragging.  I use Diskeeper which tries to 
defrag continuosly when there is no other disk IO.  But it can't keep up with 
the BE images, I have to manually defrag with Diskeeper every 3 to 4 months. :(
