The storage capability of hard drives has been increasing exponentially over the past 60 years. The IBM 350 RAMAC disk released in 1956 was able to store 2000 bits (a unit used to measure storage ability) of information per square inch. In 2014, Seagate Technology released a hard drive that could store 1 billion bits in every square inch. Now only two years later, there is talk of hard drives that can store 1.3 trillion bits per square inch!
To further improve our data storage capabilities, scientists today are working on the development of new materials to store information, such as single molecule magnets. A single molecule magnet is a molecule which can be magnetized using a magnetic field, yet still remains magnetized once the magnetic field is removed. This means that each molecule can contain 1 bit of information, allowing much more storage than the technology in computers today. (more…)
