A Minecraft user has created a working hard drive in Minecraft — albeit with a capacity of 1 kilobyte.
The drive, created by Reddit user “Smellystring”, works on a simple binary system. Instead of using magnets or transistor cells to store the data, it uses blocks that can be either solid or opaque. Reading from the disc involves beaming a redstone signal, which is roughly the Minecraft equivalent of an electrical current and will pass through the solid blocks but not the opaque ones. The drive uses solid blocks to represent 1 in binary code and opaque blocks for 0s. A virtual control room lets you “press” buttons to read from or write to the drive and even access a specific position on the drive.
