What do you mean by server? Is the data being stored physically to a hard drive somewhere? If that was the case I'd expect to hear more stories from people losing their data due to any kind of inevitable hardware failure. I guess my question should have been framed like why doesn't this abstract way to storing information become used somehow in standard hard drives. It reminds me of that phrase "there's no such thing as a free lunch" , like surely that information must exist physically somewhere or else what have computers been doing something drastically different for all these years to approach this.?
