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).

Sep 7, 2011 · Short tutorial on RAID levels 0, 1, 5, 6 and 10, the advantages of striping, mirroring and parity for performance & security plus their use for prepress storage

Jan 21, 2025 · 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.

RAID levels greater than RAID 0 provide protection against unrecoverable sector read errors, as well as against failures of whole physical drives. The term "RAID" was invented by David Patterson, Garth Gibson, and Randy Katz at the University of California, Berkeley in 1987.

Jul 23, 2019 · In this article, learn about RAID types, their pros and cons, and their use cases. RAID levels are grouped into the following categories: Additionally, you can choose how to implement RAID on your system. Therefore you can choose between hardware RAID, software RAID, and firmware RAID.

Aug 10, 2010 · RAID stands for Redundant Array of Inexpensive (Independent) Disks. On most situations you will be using one of the following four levels of RAIDs. RAID 0 RAID 1 RAID 5 RAID 10 (also known as RAID 1+0) This article explains the main difference between these raid levels along with an easy to understand diagram. In all the diagrams mentioned below:

Nov 16, 2022 · Redundant array of independent disks – abbreviated as RAID – is defined as a storage technology that combines multiple hardware disk units into a virtualized logical unit to improve the performance, reliability, and ease-of-access of data storage.

Mar 10, 2025 · RAID (Redundant Array of Independent Disks) is a data storage technology that combines multiple physical disk drives into a single logical unit to improve data redundancy, …

Oct 17, 2024 · RAID stands for Redundant Array of Independent Drives. It is a virtualization technology that creates arrays of multiple drives for performance, redundancy, backup, etc. There are different types of RAIDs with their pros and cons. However, the three main techniques in RAID are striping, mirroring, and parity.

RAID 5E, RAID 5EE, and RAID 6E (with the added E standing for Enhanced) generally refer to variants of RAID 5 or 6 with an integrated hot-spare drive, where the spare drive is an active part of the block rotation scheme.
