RAID-Z

RAID-Z is a data storage technology that protects against data loss by spreading your files across multiple hard drives with built-in error correction. Think of it as a safety net: if one drive fails, your data remains accessible and safe because the system can rebuild the missing pieces from the remaining drives. It offers a good balance between storage efficiency and fault tolerance, often used in network-attached storage (NAS) systems to ensure data integrity without sacrificing too much capacity. Essentially, RAID-Z helps keep your data secure and available even if hardware issues occur.
