A team found a way to create a mechanical memory storage system inspired from old tech, but this new system works faster than "modern" electronic memory storages.

These are not only several thousand times faster than current storage systems, but can also withstand things such as EMP bursts and Solar Flares.

The researchers used electron-beam lithography to produce the beam-and-pad design of the tiny devices, carving the switches from wafers made of single-crystal layers of silicon and silicon oxide.
The tiny dimensions of the device allowed it to vibrate quickly, achieving a millions-of-cycles-per-second frequency of 23.57 megahertz. This speed reflects the rate at which the device could "read" stored information. As a comparison, the hard drives in current laptops can read at a speed of a few hundred kilohertz (thousands of cycles per second) in actual operation. The researchers speculate that even smaller beams could be produced and that such devices could achieve true read speeds in the gigahertz range -- billions of cycles per second.
Other advantages of this tiny mechanical memory system include its angstrom-sized "range of motion," allowing it vibrate between states using only femtowatts of power, compared with the milliwatts or microwatts of power needed for read-write functions in current machines. The device also overcomes the superparamagnetic effect that limits contemporary systems, allowing the beams to be packed at densities that exceed the 100 gigabits per square inch that is the current ceiling. In addition, unlike conventional electronic or magneto-electronic storage systems, these nanomechanical memory cells are resilient in electrical and magnetic fields.
