What the bundle contains
Capacity and redundancy
The four-drive layout reserves two drive-equivalents for resilience and leaves two bays open; VM and container backups remain separate.
Approximation: $(4 - 2) × 12TB = 24TB$. Filesystem formatting, system partitions, snapshots, and RAID implementation reduce displayed free space.
