Scientists have been trying to figure out how to make data move faster without using up precious resources. They've tried moving data through physical moving discs, moving electricity, and magnetic wires, all of which have faults. Therefore, they are now testing whether sound waves can move data efficiently. If their findings bring success, computers will be able to run faster based on the types of soundwaves in the air.
| Attmpted Method | Findings |
|---|---|
| Hard disk drives | Moving parts have physical limitations. |
| Flash-based solid-state disk drives | Becomes unreliable too quickly |
| Expensive | |
| Still slow | |
| Racetrack memory: Magnetic field / Electricity | Create heat (waste) |
| Reduced power efficiency |
