Ok since nobody likes this topic but me, imma adopt it 
Here’s me copying off my two 5950x SATA 18tb dump drives* to USB connected drives that I can detach and drop off at the datacenter tomorrow.
That copy should fill those two 18tb drives, which are attached via my super complicated, sophisticated NAS. You probably can’t understand it, so don’t even try.
* It’s a good time to empty the dump drive since I had to reset all plotting when 1.1.5 was released; this 5950x is also one of my farmers. So all plots are starting from scratch, that’s at least 6 hours of nothing writing to the two dump drives.
