Ok perfect.

Something else. If you have lets say 4x5TB an 4x1TB.
And you plot first all the 4X5TB so the nonces are starting on the first and ending on the last. Then starting with the last nonces on the 1TB's. Is this the best option?
Or does it really make no difference if you first plot a 1TB, then a 500GB, then a 5TB, then again a 500GB, then maybe a 8TB.. end so on...
I just was wondering today if this make any difference in mining.. :-) 

Offcourse most people will not have this nice system unless you do al the plots again. but even then if  you somthing finds like a cheap 1TB and just want to add it after your last  5TB... then again the nice system is gone :p
