What is hard disk raw copy?
A raw disk copy is a kind of disk clone method that will copy the sectors in the hard drive including the blank ones. The other clone method is intelligent disk clone that only clone the used sectors.
For a raw disk clone, the target hard drive must have large capacity no less than the original drive that needs cloning. Obviously, a hard drive raw copy will certainly take more time than Intelligent disk clone.

Data or system migration: transfer everything on the hard drive including system to another one.
Data backup: server as a full backup original hard drive just in case data loss.
Media duplication: use it clone storage media devices including SSD, external hard drive, USB flash drive, SD card.
