If I have 2 identical hard drives with the following characteristics:
- SATA 6.0 Gb/s
- 5400 rpm
How long should a full dd copy take to complete?
So far it's been running for 5 hours and still going...
I am using Linux Ubuntu 12.04 64bit and the command I am using is:
dd if=/dev/sdb of=/dev/sdc
I can now see the progress, and it's been 6+ hours for copy 430GB. The HDD is 3TB...
Is there no faster way of doing this?
This seems a lot better than before (Thanks to Groxxda for the suggestions):
sudo dd if=/dev/sdb bs=128K | pv -s 3000G | sudo dd of=/dev/sdc bs=128K
ETA is about 9 hours for 3TB, whereas before it reached 430GB after 6 hours, so I am guessing it would have taken about 36 hours using the previous command.
