Jan 14, 2020 · RAID is a way to group multiple hard drives as one unit for faster, more reliable, or more secure data storage. Learn the differences and benefits of RAID 0, 1, 5, and 10 configurations.
RAID (/ r eɪ d /; "redundant array of inexpensive disks" or "redundant array of independent disks") is a data storage virtualization technology that combines multiple physical disk drive components into one or more logical units for the purposes of data redundancy, performance improvement, or both. This is in contrast to the previous concept ...
- RAID 0. RAID 0, sometimes referred to as striped set or striped volume, needs at least two drives. The disks are combined into a single big volume in which data is distributed uniformly throughout the array’s disks.
- RAID 1. RAID 1 is an ideal option when the main objective is data protection and redundancy. This RAID type saves your data on a single disk and a separate copy on the other available drives.
- RAID 5. This is a popular setup that effectively balances security and performance. It needs at least three disks and provides faster reading speeds but unchanged write rates.
