In the last decade, we took part in a tremendous expansion in our capabilities to both generate and collect data. Advances in scientific data collection, for example from remote sensors, or from space satellites have generated huge amounts of data. Moreover advances in data storage technology such as faster, higher capacity and cheaper storage devices, better database management systems and data warehousing technology have allowed us to transform this data into “mountains” of stored data Especially in the last case I recently read about a new device,
which should be able to store till 500 GB!
General Electric Global Research, the society that developed such a support, claims they found out a way to put up to 500GB of data on a regular-sized DVD disc under laboratory conditions.
This result has been reached by writing 3-dimensional patterns that represent data onto a disc made of highly reflective material. The disc then acts as a mirror that makes it possible for a laser to pick up the entire piece of data.
Out of consideration about such technology where I am definitely not an expert, I found that news really interesting and amazing. As a matter of fact, if we compare that with current storage, there is no chance for them: the highest capacity Blu-ray discs can store up to 50GB of data, while the most common type of DVD holds less than 9GB of information.

So, holographic disc-based storage is a long ways off from consumers, but its potential is really great in the storage community!
