Its no bugged run then! Areca Cache never scored the same in each run! It differences, same like rst.
And SSDs on southbridge are faster than ramdrive, they are only fast with Controller.
With 2 SSDs 1,3G VS is easy without tricking anything but activate write back in RST! On P45 i score 1,2 with 2 and 1,5G with 4 SSDs;)
