The best-balanced office choice combines DSM administration with 24TB dual-parity capacity and four exact CMR NAS drives.
Watch: Dual 2.5GbE helps concurrency or failover; it does not give one client 5GbE automatically.

Why this exact build
What the bundle contains
Capacity and redundancy
The four-drive pool can continue after two drives fail; team data still needs snapshots, off-site backup, and restore tests.
Approximation: (4 − 2) × 12TB = 24TB. Filesystem formatting, system partitions, snapshots, and RAID implementation reduce displayed free space.
