Storage tube - Storage

These two effects were both utilized in the construction of a storage tube. Storage was accomplished by striking any suitably long-lived phosphor with electrons with energies just above V cr1, and erased by striking them with electrons above V cr2. There were any number of varieties of mechanical layouts used to improve focus or cause the image to be refreshed either internally to the tube or through off board storage.

Energy storage - Mechanical storage

Energy can be stored in water pumped to a higher elevation using pumped storage methods or by moving solid matter to higher locations (gravity batteries). Other commercial mechanical methods include compressing air and flywheels that convert electric energy into kinetic energy and then back again when electrical demand peaks.

Object storage - Cloud storage

The vast majority of cloud storage available in the market leverages an object-storage architecture. Some notable examples are Amazon Web Services S3, which debuted in March 2006, Microsoft Azure, Rackspace Files (whose code was donated in 2010 to Openstack project and released as OpenStack Swift), and Google Cloud Storage released in May 2010.

Mass storage - Storage media

Magnetic disks are the predominant storage media in personal computers. Optical discs, however, are almost exclusively used in the large-scale distribution of retail software, music and movies because of the cost and manufacturing efficiency of the molding process used to produce DVD and compact discs and the nearly-universal presence of reader drives in personal computers and consumer appliances. Flash memory (in particular, NAND flash) has an established and growing niche as a replacement for magnetic hard disks in high performance enterprise computing installations due to its robustness stemming from its lack of moving parts, and its inherently much lower latency when compared to conventional magnetic hard drive solutions. Flash memory has also long been popular as removable storage such as USB sticks, where it de facto makes up the market. This is because it scales better cost-wise in lower capacity ranges, as well as its durability. It has also made its way onto laptops in the form of SSDs, sharing similar reasons with enterprise computing: Namely, markedly high degrees of resistance to physical impact, which is again, due to the lack of moving parts, as well as a performance increase over conventional magnetic hard disks and markedly reduced weight and power consumption. Flash has also made its way onto cell phones.

Mass storage - Storage media

The design of computer architectures and operating systems are often dictated by the mass storage and bus technology of their time.

Energy storage - Pumped-storage

At times of low electrical demand, excess generation capacity is used to pump water from a lower source into a higher reservoir. When demand grows, water is released back into a lower reservoir (or waterway or body of water) through a turbine, generating electricity. Reversible turbine-generator assemblies act as both a pump and turbine (usually a Francis turbine design). Nearly all facilities use the height difference between two water bodies. Pure pumped-storage plants shift the water between reservoirs, while the "pump-back" approach is a combination of pumped storage and conventional hydroelectric plants that use natural stream-flow.

Energy storage - Storage capacity

Storage capacity is the amount of energy extracted from a power plant energy storage system; usually measured in joules or kilowatt-hours and their multiples, it may be given in number of hours of electricity production at power plant nameplate capacity; when storage is of primary type (i.e., thermal or pumped-water), output is sourced only with the power plant embedded storage system.

Energy storage - Pumped-storage

Worldwide, pumped-storage hydroelectricity (PSH) is the largest-capacity form of active grid energy storage available, and, as of March 2012, the Electric Power Research Institute (EPRI) reports that PSH accounts for more than 99% of bulk storage capacity worldwide, representing around 127,000 MW. PSH energy efficiency varies in practice between 70% and 80%, with claims of up to 87%.

IBM Storage - Flash Storage

IBM FlashSystem offers a range of dedicated, non-SSD "all-flash" storage systems and provide flash capacity for a number of integrated systems. In April 2013, IBM announced a plan for a $1 billion investment in flash storage research and development. IBM acquired flash storage system maker Texas Memory Systems in 2012.

Object storage - Archive storage

Some early incarnations of object storage were used for archiving, as implementations were optimized for data services like immutability, not performance. EMC Centera and Hitachi HCP (formerly known as HCAP) are two commonly cited object storage products for archiving. Another example is Quantum Lattus Object Storage Platform.

Hydrogen storage - Chemical storage

Chemical storage could offer high storage performance due to the strong binding of hydrogen and the high storage densities. However, the regeneration of storage material is still an issue. A large number of chemical storage systems are under investigation, which involve hydrolysis reactions, hydrogenation/dehydrogenation reactions, ammonia borane and other boron hydrides, ammonia, and alane etc. Storage in hydrocarbons may also be successful in overcoming the issue with low density. For example, supercritical hydrogen at 30 °C and 500 bar only has a density of 15.0 mol/L while methanol has a density of 49.5 mol H 2 /L methanol and saturated dimethyl ether at 30 °C and 7 bar has a density of 42.1 mol H 2 /L dimethyl ether. These liquids would use much smaller, cheaper, safer storage tanks. The most promising chemical approach is electrochemical hydrogen storage, as the release of hydrogen can be controlled by the applied electricity. Most of the materials listed below can be directly used for electrochemical hydrogen storage.

Self storage - Storage auctions

In the fall of 2010, two new television programs featuring storage auctions, Storage Wars and Auction Hunters, were released. The popularity led to additional shows such as Storage Hunters, Storage Wars: Texas, and Storage Wars: New York which helped increase the visibility and interest of storage auctions. Storage Wars: Canada also debuted on the Outdoor Living Network in 2013.

Energy storage - Thermal storage

Thermal energy storage (TES) is the temporary storage or removal of heat.

External storage - Optical storage

Optical storage devices have media that use laser light technology for data storage and retrieval.

Self storage - Storage auctions

In the United States, self-storage facilities may hold storage auctions or lien sales to vacate non-paying tenants according to their enforcement rights that are outlined within the lien law of each jurisdiction.

Object storage - Hybrid storage

A few object-storage systems, such as Ceph, GlusterFS, Cloudian, IBM Spectrum Scale, and Scality support Unified File and Object (UFO) storage, allowing some clients to store objects on a storage system while simultaneously other clients store files on the same storage system. While "hybrid storage" is not a widely accepted term for this concept, interoperable interfaces to the same set of data are becoming available in some object-storage products.

Compressed-air energy storage - Storage

Air storage vessels vary in the thermodynamic conditions of the storage, and on the technology used:

Computer data storage - Primary storage

Primary storage (also known as main memory, internal memory or prime memory), often referred to simply as memory, is the only one directly accessible to the CPU. The CPU continuously reads instructions stored there and executes them as required. Any data actively operated on is also stored there in uniform manner.

Sweet potato storage - Indoor storage

Sweet potatoes may be harvested and stored in building. This could include in the living area or in a granary built specifically to store produce. In home storage is typically done in straw woven baskets, cloth bags or wooden boxes. Baskets and boxes have been shown to be more effective at minimizing mechanical damage. If possible tubers should be kept off of the ground to keep them away from rodents and other pests. This is an effective technique for maintaining proper ventilation though depending on the type of building maintaining proper storage temperature and RH may be difficult.

Storage area network - Storage layer

On top of the Fibre Channel-Switched Protocol is often the serialized Small Computer Systems Interface (SCSI) protocol, implemented in servers and SAN storage devices. It allows software applications to communicate, or encode data, for storage devices. The internet Small Computer Systems Interface (iSCSI) over Ethernet and the Infiniband protocols may also be found implemented in SANs, but are often bridged into the Fibre Channel SAN. However, Infiniband and iSCSI storage devices, in particular, disk arrays, are available.
