first time ever, I have 16GB and it helps me defrag the plots. I use fastcopy x64 with a 12 GB buffer to transfer a fragmented plot from one drive to another eliminating the fragments. Also great with plot optimiser. I switched the swapfile off in windows its much more responsive in windows 10 and most of the snappy GUI in this version doesnt actually mean its a responsive system. My theory is windows 7 pushed the boundaries with GPU assisted GUI for glass effects now its all slate with later versions just makes it snappy on the surface through gpu.
