Indeed, that sounds really slow: ( 138GB * 1000MB/GB ) / (26hr * 60min/hr * 60s/min ) = 1.5 MB/s ~ 12 Mbps
That's in the USB1.x range. If you use USB3.0 and can get 100MB/s write speed, you'd be done in about 6 hours. Have a look at hdparm to get some info on read/write performance of your drive: https://linuxconfig.org/hard-drive-speed-test-using-linux-command-line-and-hdparm Good luck and let us know what you discover.
