Bestseller
1
Mirrors data across two disks, providing full redundancy at the cost of halved storage capacity.
Best for environments where data protection is critical, ensuring data availability even if one disk fails.
Bestseller
5
Stripes data and parity across multiple disks, offering a balance of performance and fault tolerance.
Suitable for general-purpose storage needs, providing data recovery capabilities with efficient use of disk space.
Bestseller
