Berkeley Lab researchers have created a unique ultra-high density memory storage medium that can preserve digital data for a billion years. The new technology also has the potential to pack thousands of times more data into one square inch of space than today's chips.The technology could be on the market within the next two years.

The video shows an iron nanoparticle, approximately 1/50,000th the width of a human hair, that in the presence of a low voltage electrical current can be shuttled back and forth inside a hollow carbon nanotube with remarkable precision.
Courtesy Arnold ReinholdI bought a hard drive yesterday that can store a million MB of data for $202. That is about 20 cents per megabyte. My first hard drive purchase cost over $600 for just one megabyte.
The first computer I got to play with used relays. I programmed it by moving wires creating a circuit called a "flip flop" that could play tic-tac-toe. The relays used electromagnets to open and close electrical contacts and if a bug got in between the contacts the program failed to work and had to be "debugged".
When I switched majors in college from engineering into education I needed to take a foreign language. Luckily I was allowed to use my class in Fortran (a computer language) to qualify. In the Fortran coarse we stored instruction data on punch cards. The holes in the cards allowed electrical contact between appropriate circuits within a huge mainframe computer.
Before I had enough money to buy that first hard drive, I used magnetic tape. Audio pulses on a regular audio cassette would be converted to connections being made within an integrated circuit comprised of millions of transistor switching circuits.
Soon personal memory devices will hold thousands of movies, run for weeks on one battery, and will last for decades.
IBM just announced another breakthrough in data storage that could lead to electronic devices capable of storing far more data in the same amount of space than is possible today, with lightning-fast boot times, far lower cost and unprecedented stability and durability.
