linux:dd

Clone a drive with dd and show progress

dd if=<source> of=<target> bs=4M conv=noerror,sync

The bs (block size) of 4MB works well with two SSD's. The use of conv=noerror,sync is rather disputable: noerror will continue ignoring errors and sync will fill the blocks - I think I use conv forever and it lost it's value with modern drives - I think it doesn't hurt …
