RAID levels share the following properties: * Several different physical disks are combined and accessed as a compound element. Under Linux, this is done by the driver for multiple devices, also known as /dev/md*. * The stored data is distributed over all disks in a well-defined way. * The data is stored in a redundant way over the disks, so in case of failure, data is recoverable.

All RAID levels involve the use of multiple hard drives to increase performance, reliability, or a combination of both. They use different techniques such as data striping, mirroring, or parity to achieve these goals. RAID levels also provide fault tolerance to protect data in case of a drive failure.
