FumeFX - Arnold Volume
The FumeFX - Arnold Volume is very similar in functionality to the Arnold Volume Object. It is actually an object that loads FumeFX caches and provides channel access to the Arnold's shader network. Integration within the FumeFX grid allows intuitive support of all the cache manipulation options.
FumeFX - Arnold Volume supports Draft Mode option 
from the FumeFX attribute editor which allows faster rendering of FumeFX grid at reduced resolution and lower memory consumption.
