The smart-alec answer would be... "Veritas, of course!"

But seriously, it depends on many factors you have not provided
information about.

-> Different operating systems support different filesystems; you
   should probably specify what OS you are using.

-> Hardware choices have ENORMOUSLY more impact on speed than any
   choice of filesystems.

If your hardware is too slow, changing filesystems will not help you.

And you would be _way_ better off with a filesystem that is 3% slower
if it improves reliability by a significant factor.
