Please forgive me if this is a stupid question, but couldn’t you just buy an air-isolated hard drive of several TB and never access it from a computer that was connected to a network either by cable or wifi?
I guess I don’t really understand what this thing is, and I may be at a point in my life at which it is not possible to explain it to me. I do know enough not to use clouds, however, and to only buy dumb appliances.
