RAID (/ reɪd /; redundant array of inexpensive disks or redundant array of independent disks) [1][2] is a data storage virtualization technology that combines multiple physical data storage components into one or more logical units for the purposes of data redundancy, performance improvement, or both.

2020年1月14日 · RAID is an acronym for “redundant array of independent drives (or disks).” Basically, RAID lets you take several hard drives and group them as one unit. This can help you store backups of your data in case a drive fails, or improve the speed and efficiency of …

2011年9月7日 · RAID is a technology that is used to increase the performance and/or reliability of data storage. The abbreviation stands for either Redundant Array of Independent Drives or Redundant Array of Inexpensive Disks, which is older and less used. A RAID system consists of two or more drives working in parallel.

RAID (redundant array of independent disks) is a way of storing the same data in different places on multiple hard disks or solid-state drives to protect data in the case of a drive failure. There are different RAID levels, however, and not all have the goal of providing redundancy .

In computer storage, the standard RAID levels comprise a basic set of RAID ("redundant array of independent disks" or "redundant array of inexpensive disks") configurations that employ the techniques of striping, mirroring, or parity to create large reliable data stores from multiple general-purpose computer hard disk drives (HDDs). The most ...

2023年11月15日 · RAID is a common method for protecting application data on HDDs and solid-state storage, with different types of RAID balancing the level of protection and performance against the cost. The greater the performance or the level of protection, the higher the cost.

2014年3月27日 · RAID stands for Redundant Array of Inexpensive (or sometimes "Independent") Disks. In general, a RAID-enabled system uses two or more hard disks to improve the...

2025年1月21日 · RAID (Redundant Arrays of Independent Disks) is a technique that makes use of a combination of multiple disks for storing the data instead of using a single disk for increased performance, data redundancy, or to protect data in the case of a drive failure.

2019年7月23日 · RAID (redundant array of independent disks) is a setup consisting of multiple disks for data storage. They are linked together to prevent data loss and/or speed up performance. Having multiple disks allows the employment of various techniques like disk striping, disk mirroring, and parity.

RAID – or Redundant Array of Independent Disks – is a type of storage that writes data across multiple drives within the same system. Different configurations are expressed as numbers, such as RAID 0, RAID 1, or RAID 5.
