This has no meaning that I'm aware of.

If you have 1.6Tb available, which are you limiting it 1.0 Tb?
I have a good sized disk as holding disk, and I have that set to "use
-500Mb" meaning it will use all but 500 megs of a .6Tb partition just for
my stuff here at home. Average total for 2 machines is about 30Gb so that
fits nicely.
Also, except for my /usr/movies/ directory, I have the dle's defined to not
have more than 10Gb in any one dle. Obviously, when its time for a level 0
on movies, then everything else gets scheduled for about a level 2. I've
done a few weddings and they are bulky in raw.
You might have better results breaking up some of the bigger DLE's into
smaller pieces.
