The UN created FAOSTAT with the aim of helping scientists feed the world

Monitoring the global food supply involves tracking data on agriculture, land use, fishing, forestry, food aid, nutrition and population growth. To make sense of it all, researchers at the Food and Agriculture Organization (FAO) of the United Nations built FAOSTAT, the world's largest database of food and agricultural information, with more than a million statistics covering five decades and 245 countries and territories.
The FBI's CODIS database solves cold cases with genetic data

In 1990, when the FBI began building its master DNA database—the Combined DNA Index System, or CODIS—investigators could generally use DNA analysis only for cases in which they possessed both crime-scene evidence and a specific suspect. Not anymore.
Researchers at IBM's Almaden, California research lab are building what will be the world's largest data array--a monstrous repository of 200,000 individual hard drives all interlaced. All together, it has a storage capacity of 120 petabytes, or 120 million gigabytes.
Finding a physical space to store our voluminous cloud-based data is a problem, sure, but keeping the servers cooled down is another, much bigger problem--and an environmentally unfriendly one at that. Instead of installing expensive cooling systems, future networked data centers could use the waste heat of computing to keep people warm.
If you could put all the data in the world onto CDs and stack them up, the pile would stretch from the Earth to beyond the moon, according to a new study. The world’s technological infrastructure has a staggering capacity to store and process information, reaching 295 exabytes in 2007, a reflection of the world’s almost complete transition into the digital realm. That's a number with 20 zeroes behind it, in case you're wondering.
We always knew that the National Security Agency collects a lot of surveillance data from satellites and by other means, but we never quite imagined it was this much: the NSA estimates it will have enough data by 2015 to fill a million datacenters spread across the equivalent combined area of Delaware and Rhode Island. The NSA wants to store yottabytes of data, and one yottabyte comes to 1,000,000,000,000,000 GB.
In the data storage arena, developing smaller systems has always been the name of the game. But UK researchers have discovered that the tiny eyes of the mantis shrimp have held the secret to optimizing optical data systems all along. By mimicking the natural design of the mantis shrimp eye, researchers think they can enhance the capacity of media like CDs, DVDs and data projectors.
Even though computer memory has become cheaper and cheaper, the materials chemistry behind storage has not changed significantly in a long time. Now, thanks to a breakthrough by Korean scientists, that's all about to change.
A holographic disc that can store 100 DVDs' worth of data and lasts a century

Today, General Electric unveiled a next-generation optical storage technology that can pack as much as 20 Blu-Ray discs or a hundred DVDs' worth of data onto a single disc. The newly devised discs, which use holograms to store data in the form of bits, can hold 500 gigabytes of information, the company says.
Backing up my computer’s hard drive has always been like flossing: I know I should be doing it even though it’s one of life’s more prickly pains in the butt. Both chores are the kinds of thing you can never fully appreciate until something goes horribly wrong, like a hard drive fries or some teeth start jiggling loose.
