Description
The Synology DX1222 is a high-density storage expansion solution designed to scale your data infrastructure effortlessly. By connecting via a dedicated expansion cable, it allows users to add up to 12 additional 3.5-inch or 2.5-inch SATA drives to compatible host NAS units. This unit eliminates the need for complex reconfigurations, supporting online volume expansion to ensure business continuity and maximum uptime for critical services.
This product is for:
- Creative professionals managing massive 4K/8K video libraries who need immediate storage overhead.
- Small to medium-sized businesses requiring a cost-effective local backup target for disaster recovery.
- IT administrators looking to scale existing Synology deployments without replacing the primary host unit.
- Surveillance operators needing extended retention periods for high-definition NVR recordings.
- Data-intensive home lab enthusiasts hosting large-scale virtualization or media server environments.

- Drive Bays: 12 x 3.5" or 2.5" SATA HDD/SSD
- Hot Swappable Drive: Yes
- Connection Port: 1 x Expansion Port
- Power Recovery: Synchronized with the host DiskStation
- Cooling System: 2 x 120mm system fans with adjustable speed modes
- Form Factor: Desktop
- Maximum Internal Raw Capacity: Dependent on host NAS limits
Setting up the DX1222 is remarkably straightforward thanks to its plug-and-play architecture. Once connected to a compatible host, the new drives appear in the Synology Storage Manager, allowing for the creation of new volumes or the expansion of existing RAID groups. The synchronized power-on/off feature ensures that the expansion unit behaves as an integrated part of the main server, reducing management overhead and power consumption during idle periods while maintaining high-speed data throughput.
Unlike standard USB or eSATA external enclosures, the DX1222 utilizes a high-bandwidth expansion cable that ensures data integrity and performance comparable to internal drives. While the DX517 offers a smaller 5-bay footprint for home users, the DX1222 is the definitive choice for enterprise-grade scaling, offering more than double the capacity in a single chassis for high-performance DS-series models. It provides a more stable and manageable alternative to managing multiple smaller external drives.
Q&A:
- Does the DX1222 require a separate DSM installation? No, it is managed entirely through the host Synology NAS operating system.
- Can I use the DX1222 as a standalone NAS? No, it functions strictly as an expansion unit and requires a compatible host Synology device to operate.
- Are the drive trays tool-less? Yes, the 3.5-inch drive trays feature a tool-less design for rapid installation and replacement.
- What happens if the expansion cable is disconnected? The host NAS will trigger an alert; however, the DX1222 is designed with secure screw-in connectors to prevent accidental disconnection.
- Does it support both HDD and SSD? Yes, it supports 3.5-inch SATA HDDs and 2.5-inch SATA SSDs for versatile storage tiering and caching.
