After a month of waiting for confirmation of the bug, I have reformatted the partition as ext4. If this works (can copy 1.5TB in less than 2 days) the bug is in the NTFS support in Ubuntu. If it doesn't, I will return the drive (Seagate says it is in warranty but refuses to provide any support to Linux users) and chalk up another Ubuntu bug that is being ignored by the Ubuntu community.

Status in linux package in Ubuntu: Incomplete Bug description: I am trying to recover data from an HFS+ files system on a 4TB external USB 3 drive. Copying 3TB from the 4TB HFS+ drive to a 4TB NTFS drive using MATE Terminal cp -anR from to took 2 days. When I try to copy the same data to a 6TB NTFS USB 3 drive the results are glacial. 750GB has taken over 6 days. Obviously there is a problem of scale drive in Ubuntu MATE. I invite the developers to plug in a 12TB drive and see just how glacial (no - not glacial, more on the order of plate techtonics) slow their design is.
