Synology DX1222 - NAS expansion unit, black

The Synology DX1222 is a 12-bay desktop expansion unit for compatible Synology DiskStation systems. It adds twelve drive bays, allowing you to scale storage volumes without replacing your primary NAS. The unit supports both 2.5-inch and 3.5-inch SATA I, II, and III drives. You can perform online RAID expansion or migration while the system is running. It is designed for environments that require significant storage capacity, such as large media libraries or small-office servers.

Housed in a black chassis, the unit weighs 9.02 kg. Two 120 mm fans provide cooling and operate at 24.6 dB, ensuring quiet performance even during intensive data access. The hot-swap drive bays allow you to replace or add disks without powering down the device. As volume expansion is managed online, existing network services continue to run without interruption.
