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.
