Program to copy one to multiple disk, idea?

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

keys: copy to ram, buffer.

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?. :face_with_open_eyes_and_hand_over_mouth:

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.
