raid groups

Raid groups are collections of multiple hard drives or storage devices working together to improve performance, reliability, or both. By combining drives in specific configurations called RAID levels, data can be protected from loss if a drive fails, or read/write speeds can be increased. For example, some setups mirror data across drives for safety, while others split data to speed up access. RAID groups are commonly used in servers and high-performance systems to ensure data is secure and accessible efficiently.
