Our research has shown Reiserfs to be the fastest. All Linux FS suffer 
from the block allocation issues. That is the fact the files are 
allocated based based on a 4k block, but most water tiles are only 130 
bytes but use up 4k of disk. We have found some SAN devices that do 
their own internal space allocation that does not suffer from this 
effect, but I believe that is specific to the internal SAN implementations.
