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).

RAID stands for Redundant Array of Independent Disks and is a form of data management/backup that spreads your data across multiple hard drives. To learn more about what RAID is, visit this page. Table of Different RAID Levels

There are many different ways to organize data in a RAID array. These ways are called "RAID levels". Different RAID levels have different speed and fault tolerance properties. RAID level 0 is not fault tolerant.

Each scheme, or RAID level, provides a different balance among the key goals: reliability, availability, performance, and capacity. RAID levels greater than RAID 0 provide protection against unrecoverable sector read errors, as well as against failures of whole physical drives.

Use this RAID calculator to easily calculate RAID capacity, disk space utilization, cost per usable TB, read/write efficiency (I/O operations per second improvement) and more. Supported levels are: RAID 0, RAID 1, RAID 1E, RAID 4, RAID 5, RAID 5E/EE, RAID 6, RAID 10, RAID 50, and RAID 60. What is RAID? How to calculate RAID capacity?

There are several RAID level choices: RAID 0, 1, 3, 5, 1+0, 3+0 (30), and 5+0 (50). RAID levels 1, 3, and 5 are the most commonly used. The following table provides a brief overview of the RAID levels.

RAID has developed since its original definition in 1987. Due to technical progress some RAID levels are now practically meaningless, whilst others have been modified or added at a later date. This section introduces the RAID levels that are currently the most significant in practice.
