How about an option to verify multiple times after a successful copy with options to set different algorithms to each activated testers?
I dont think it is time efficient, because you are doing the same thing multiple times, plus, some hashing algorithms are slow as hell. I think the best idea is to use a hashing that is efficient and also "collision free" (it means, the hashing is safer to use). One algorithm that fit both purposes is BLAKE2.
