Question

Accepted Answer

RAID (Redundant Array of Independent Disks) is a data storage technology that combines multiple physical drives into a single logical unit for improved performance, fault tolerance, and data protection.

RAID is used to increase storage capacity, enhance data reliability, and improve read/write performance.
There are different RAID levels, such as RAID 0, RAID 1, RAID 5, RAID 10, etc., each offering different benefits and trade-offs.
RAID 0 stripes data across multiple drives to improve performance but offers no redundancy.
RAID 1 mirrors data across multiple drives for fault tolerance but reduces storage capacity.
RAID 5 uses block-level striping with distributed parity to provide fault tolerance and improved performance.
RAID 10 combines mirroring and striping to offer both redundancy and performance benefits.
RAID arrays can be implemented using hardware controllers or software-based solutions.
RAID technology is commonly used in servers, NAS devices, and high-performance computing systems.
