Built on our award-winning BeyondRAID technology, the Drobo 5C protects your data without any intervention - even in the event of multiple drive failures. You can even switch from single to dual disk redundancy with a single click, ensuring enterprise-level dual parity data protection when required. Drobo's with BeyondRAID are also self-healing and have virtual hot-spares. If a drive happens to fail, Drobo will automatically re-layout the data to return to a protected state without disruption.
