What is RAID?
RAID (Redundant Array of Independent Disks) is like having backup copies of your important files stored in different places on several hard drives or solid-state drives (SSDs). If one drive stops working, your data is still safe because you have other copies stored on the other drives. It’s like having a safety net to protect your files from being lost if one of your drives breaks down.
RAID (Redundant Array of Independent Disks) in a Database Management System (DBMS) is a technology that combines multiple physical disk drives into a single logical unit for data storage. The main purpose of RAID is to improve data reliability, availability, and performance. There are different levels of RAID, each offering a balance of these benefits.
RAID (Redundant Arrays of Independent Disks)
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. The term was defined by David Patterson, Garth A. Gibson, and Randy Katz at the University of California, Berkeley in 1987. In this article, we are going to discuss RAID and types of RAID their Advantages and disadvantages in detail.
