Amazon S3 Glacier is an online file storage web service that provides storage for data archiving and backup. [ 2 ] Glacier is part of the Amazon Web Services suite of cloud computing services, and is designed for long-term storage of data that is infrequently accessed and for which retrieval latency times of 3 to 5 hours are acceptable.
Hierarchical storage management (HSM), also known as tiered storage, [1] is a data storage and data management technique that automatically moves data between high-cost and low-cost storage media. HSM systems exist because high-speed storage devices, such as solid-state drive arrays, are more expensive (per byte stored) than slower devices ...
Synology also marketed a CS (CubeStation) line of four-bay storage products, with the approximate shape of a cube, [13] but later folded these into the DS line. In a review for SmallNetBuilder , Jim Buzbee was "impressed with the maturity of the DS-101's software and documentation" but felt the main negatives were "high cost and limited ...
Block-level storage is a concept in cloud-hosted data persistence where cloud services emulate the behaviour of a traditional block device, such as a physical hard drive. [1] Storage in such services is organised as blocks. This emulates the type of behaviour seen in traditional disks or tape storage through storage virtualization. Blocks are ...
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.
In computer architecture, the memory hierarchy separates computer storage into a hierarchy based on response time. Since response time, complexity , and capacity are related, the levels may also be distinguished by their performance and controlling technologies. [ 1 ]
An example of a recursive hierarchy is the Domain name system. An example of a non-recursive hierarchy are Uniform Resource Name representing an Internet Assigned Numbers Authority (IANA) number. Hierarchical namespace breakdown for urn:isbn:978-3-16-148410-0 , an identifier for the book The Logic of Scientific Discovery by Karl Popper, 10th ...
