 Use RAID 0 when you prioritize performance and are not concerned about data loss. Ideal for temporary, high-speed storage (video editing, AI workloads, etc). Not suitable for long-term storage, as one failure means total data loss.

 ### Data Integrity
 
 ZFS continuously checks that your stored data hasn't become corrupted. Every block of data is associated with a checksum, allowing ZFS to detect even the smallest alteration. If corruption is found and a healthy copy exists elsewhere, ZFS can repair the data automatically.
