I need to transfer a large (multi-terabyte) file from one Linux computer to another. I have a 1TB external SSD drive that seems like it's the fastest way in terms of bandwidth. My best guess right now is to use split to split up the big file into 2-3 smaller chunks and then copy those chunks individually. But this will use up a few extra TB on both the source and destination computers, which is a problem.

Is there a more space or time efficient way to transfer a large file from one computer to another using an external drive?

  • If both computers are on the same network, I would seriously consider transferring it via the LAN... it'll be a lot less hassle. If I have to wait 1 hour for an answer like this, it's already too much for me. With a 30mbps connection I could transfer 10G in about 45 minutes! – Jakke Jul 09 '14 at 00:30

what about dd:

srchost:$ dd if=/sourcefile of=/dev/ssd1 bs=1G count=1000 skip=[0,1000,...]

move disk... 

dsthost:$ dd if=/dev/ssd1 bs=1G >> /finalfile
