IBM have announced the world's highest capacity mobile hard disk drive at 80 GB, which they say is made possible by enhancements to the company's patented "pixie dust" technology, boosting storage density by 100 percent. If that wasn't good enough news for you, IBM also plans to launch 7,200 RPM drives for notebooks. Wow!

The new Travelstar 80GN breaks current areal density records by allowing up to 70 billion bits of data to be written on each square inch of disk space. IBM achieved this by adding another coating of "pixie dust" -- or an additional ruthenium/magnetic layer to create a five-layer sandwich called laminated-"pixie dust.".
