Fancy a Million-Gigabtye Hard Drive?

Researchers have finally found a way to create storage devices that are capable of storing millions of gigabytes of data. With the use of ferroelectric, the researchers from Drexel University and University of Pennsylvania are able to squeeze 12.8 million gigabytes of information into a cubic centimeter. Very amazing indeed.

Until recently, researchers were not able to find a method of stabilizing ferroelectricity on the nano-scale. It was this group of talented researchers that found out that water is in fact the answer to their problem. It has to do with the hydroxyl (OH) ions molecules found in water, which are capable of screening the charges.

Imagine the possibility of million-gigabyte hard drives. The amount of disk space might seem excessively generous, but I trust that when these drives become a reality, applications that truly leverage the obscene amount of space will start to sprout.

However, several researchers have suggested that significant challenges still lie ahead, such as methods of assembling the nanowires densely and efficiently reading and writing data to and from the nanowires.
