Building a computer in Minecraft is impressive. Building a data storage system which can actually hold real-world data is something else. But thats exactly what Corey Littley, a Computer Science PhD student from Michigan, created in the virtual world. Sure, the hard drive he made is only 1 kilobyte in size barely enough to store a single text file, let alone any images or videos. But its the principle of the thing that matters, because even thinking about building something like this would give the average person a splitting headache. Its another creation which illustrates just how wonderfully inventive we humans can be. Again, Im not going to try and explain how it works because I havent got the foggiest apart from it uses translucent and opaque blocks to differentiate between binary switches but it can actually read a file which is up to a kilobyte in size (although youd have to enter each byte manually), store it within the mainframe, and then retrieve the file to write it somewhere else. Like a real hard drive does. Bigger files need bigger hard drives, but unfortunately Minecrafts render distance limits how big the machine can be - so dont get rid of your old hard drives just yet.
