Storage Redundancy Modes
Storage Redundancy Modes lists documented ways a music server combines or protects its internal drives. The listed arrangements do not all provide protection against drive failure.
RAID 0 stripes data across drives without redundancy. Mirroring keeps copies across drives; other RAID levels use different combinations of mirroring, striping or parity.
Storage Redundancy Modes — Music Server
For a music server, check the supported mode, required number of drives and usable capacity. Two drives do not automatically mean mirroring is available or enabled. If the maker says mirrored without naming a RAID level, preserve that wording.
A fault-tolerant arrangement can keep data available through drive failures, but its limits depend on the mode and configuration. Follow the manufacturer’s recovery instructions rather than assuming any failed drive can be removed safely during operation.
Redundancy is not an independent backup: accidental deletion or corruption can affect the protected array too. Keep library backups separate, and do not interpret an empty specification as a documented RAID mode.
