Computer data storage

data storage device

storage of digital data readable by computers

Copy-on-write (COW), also called implicit sharing or shadowing, is a resource-management technique used in programming to manage shared data efficiently. Instead of copying data right away when multiple programs use it, the same data is shared between programs until one tries to modify it. If no changes are made, no private copy is created, saving resources. A copy is only made when needed, ensuring each program has its own version when modifications occur. This technique is commonly applied to memory, files, and data structures.

computer architecture that classifies memory/storage into a hierarchy based on response time

external computer storage, accessed directly by a single host over a local computer bus and/or interface (as opposed to a network)

sequence of bytes or bits, having a nominal length (a block size)

flexible method of allocating computer storage space to logical volumes

computer data storage architecture that manages data as objects

Early color photography method

technology which automatically moves computer data between different storage technologies (such as disk and magnetic tape)

controller for disk storage, usually integrated into the drive

data missing or collected but not analysed

disk storage system which contains multiple disk drives

the sampling frequency of a digital audio device

providing to a computer system a logical view of physical storage

Everpure, Inc. (formerly known as Pure Storage) is an American publicly traded technology company headquartered in Santa Clara, California, United States. It develops all-flash data storage hardware and software products. Pure Storage was founded in 2009 and developed its products in stealth mode until 2011. Afterwards, the company grew in revenues by about 50% per quarter and raised more than $470 million in venture capital funding, before going public in 2015. Initially, Pure Storage developed the software for storage controllers and used generic flash storage hardware. Pure Storage finished
