Hi everyone 
, i need console program to copy from one hard disk to multiple disk, at maximum speed of origin.
origin -> disk1, disk2, disk3, etc

dd if you are on linux.
Maybe the 'dd' crate I have not tested if you want a rust version.
command dd in linux. how to do that?. 
Please type man dd and try to figure out how to use it, then ask any specific questions you have.

I think I might have steered you off. dd by itself will just do one to one transfer.
The top SO answer here using tee is the best I can find.
Sorry we misled you on dd.
