My first plot just to test, using the plotter built into the official burst wallet (xplotter i think judging by the screenshots of others?).
CPU : i7 4790K (4.0 GHz)
RAM : 8GB DDR3, 1600MHz i think.
Drive : USB3 seagate barracude 4TB, 7200rpm
Plot size : 525GB
Time taken : 4 hours
Speed : 12,000 NPM
Will try the GPU plotter when i stop getting the out_of_resources message on kernel launch.
