(RAID) is a method used to combine multiple hard drives into a single logical unit to improve performance, data redundancy, or both. There are several RAID levels that offer different configurations and benefits.
, also known as , splits data evenly across multiple disks without . This can improve performance by allowing multiple disks to read and write data simultaneously.
, or , duplicates data across two or more disks to provide redundancy in case of disk failure. While it requires more storage space, it offers increased reliability and fault tolerance.
uses striping like RAID 0, but also includes parity information distributed across all disks. This allows for data recovery in case of a single disk failure.
combines mirroring and striping by creating multiple mirrored sets of striped drives. This offers both redundancy and performance benefits, making it a popular choice for many organizations looking for a balance between speed and reliability.
