Data storage is the recording (storing) of information in a storage medium. Handwriting, phonographic recording, magnetic tape, and optical discs are all examples of storage media. Biological molecules such as RNA and DNA are considered by some as data storage. [1] [2] Recording may be accomplished with virtually any form of energy. Electronic ...
Optical storage refers to a class of data storage systems that use light to read or write data to an underlying optical media.Although a number of optical formats have been used over time, the most common examples are optical disks like the compact disc (CD) and DVD.
Energy storage Magnesium battery: Early commercialization Energy storage Molten salt reactor: Research, experiments Electricity and heat generation Nanowire battery: Experiments, prototypes [62] [63] Laptops, mobile phones, long-range electric cars; storing energy for electric grid: Nantenna: Research [64] [65] [66] Electricity generation
Computer data storage or digital data storage is a technology consisting of computer components and recording media that are used to retain digital data. It is a core function and fundamental component of computers. [1]: 15–16 The central processing unit (CPU) of a computer is what manipulates data by performing computations.
3D optical data storage (not a single technology, examples are Hyper CD-ROM and Fluorescent Multilayer Disc) In 2004, development of the Holographic Versatile Disc (HVD) commenced, which promised the storage of several terabytes of data per disc. However, development stagnated towards the late 2000s due to lack of funding.
5D optical data storage (also branded as Superman memory crystal, [1] a reference to the Kryptonian memory crystals from the Superman franchise) is an experimental nanostructured glass for permanently recording digital data using a femtosecond laser writing process. [2]

An illustration of the write amplification phenomenon in flash-based storage devices. Over time, advancements in central processing unit (CPU) speed has driven innovation in secondary storage technology. [7] One such innovation, flash memory, is a non-volatile storage medium that can be electrically erased and reprogrammed.
