Who it fits
Good fit for
This unit suits users with existing Synology NAS systems who need significant storage growth without replacing their main enclosure. The redundant power supply makes it ideal for critical data environments where downtime is unacceptable. If you already use Synology DSM, adding this expansion unit is straightforward. It is perfect for small to medium businesses that require high capacity and reliability. The diskless design lets you select drives that match your specific performance and capacity needs.
Who should skip it
You should look elsewhere if you do not own a compatible Synology NAS. This is an expansion unit, not a standalone system, so it cannot operate independently. It is also not suitable for users who want a complete package with pre-installed drives. If you need a compact solution, the large footprint and 38.5-pound weight may be impractical for small offices. Additionally, if you prefer non-Synology ecosystems, this hardware will not integrate with your current setup.
Verdict: The Synology RX1223RP is a robust expansion solution for existing Synology users needing more bays and power redundancy. It delivers reliable storage growth through seamless DSM integration.
Key specs explained
Drive Bays: 12-Bay
This chassis provides twelve slots for 3.5-inch or 2.5-inch SATA drives. You can mix hard drives and solid-state drives to suit your needs. This capacity allows you to significantly expand your existing Synology NAS without buying a new primary unit. It is ideal for users who need more storage volume but want to keep their current system configuration intact.
Included Storage: Diskless
The unit arrives without any hard drives installed. You must purchase your own drives separately. This gives you the freedom to choose specific drives based on your performance and capacity requirements. It is a cost-effective option if you already have spare drives or want to select drives tailored to your specific workload rather than accepting pre-installed options.
Redundant power supply
The device includes two power supplies to prevent a single point of failure. If one power unit fails, the other keeps the drives running. This feature is critical for maintaining data availability in a business or serious home office environment. It ensures that your storage expansion remains online even during power supply issues, protecting your data from unexpected downtime.
Weight: 38.5 pounds
The unit weighs 38.5 pounds due to its metal chassis and dual power supplies. You need a sturdy desk or rack that can support this weight. Ensure your mounting surface is level and strong enough to handle the load. This heft indicates a durable build quality designed to withstand continuous operation, but it requires careful placement in your workspace.
Design and build overview
The Synology RX1223RP is a black expansion chassis built for serious storage growth. According to the listing, it measures 16.9 inches by 27.2 inches by 3.5 inches.

The large footprint requires careful placement in your server room or home office. You must ensure you have enough floor space to accommodate its width and depth.
This unit is diskless, meaning it contains no pre-installed drives. You must purchase your own 3.5-inch or 2.5-inch SATA drives separately. This design allows you to choose the exact storage capacity and type you need. The layout focuses on drive access and power redundancy. The redundant power supply is a key feature that prevents single points of failure. This means if one power unit fails, the other keeps your data safe. The finish is a simple black color that blends into most technical environments. There are no flashy lights or decorative elements. The design prioritizes function over form. You get a reliable, utilitarian box that expands your existing Synology NAS system. It is built to integrate seamlessly with DSM tools for easy management. The build quality supports long-term use in demanding conditions.
Setup and everyday use guide
This unit is diskless, so you must install your own drives first. You can use any 3.5-inch or 2.5-inch SATA hard drives or solid-state drives. This gives you full control over your storage media. Synology notes that their own drives offer the best integration and reliability, but third-party SATA drives are supported. Once your drives are seated, you connect the expansion unit to your main Synology NAS via the data cable. The listing states you can gain storage expansion in minutes using Synology DSM unified tools. This means the setup process is managed through the same interface you already use for your primary server. You do not need separate management software. The redundant power supply is a key feature for daily stability. It prevents single points of failure. If one power supply unit fails, the other keeps the drives running. This design supports continuous operation without immediate downtime. The unit is black and measures 16.9 by 27.2 by 3.5 inches. It weighs 38.5 pounds. This mass suggests a sturdy build that stays in place during operation. Daily use involves managing this additional space through your existing DSM environment. The system treats the extra bays as part of your total storage pool. You can create volumes or add storage to existing ones directly from the web interface. The five-year limited warranty covers the hardware, providing long-term support for your investment.
Before You Buy This Expansion Unit
This expansion unit requires a compatible Synology NAS to function. It does not operate as a standalone storage device. You must verify that your primary system supports the RX1223RP model. Check the Synology compatibility list before purchasing. The chassis is diskless, meaning you need to buy twelve SATA drives separately. These can be 3.5-inch or 2.5-inch models. Ensure your existing NAS has enough ports and power for the connection. The redundant power supplies help maintain uptime during failures. This feature is critical for business environments where data availability is paramount. You should plan for adequate ventilation around the unit. Its large footprint requires significant desk or rack space. Consider the weight when selecting a mounting solution. This product suits users who need to scale storage without migrating data. It complements other NAS drives by adding capacity rather than replacing them. Regular firmware updates via DSM will keep the system stable. Keep an eye on drive health through the management interface.
Check before you buy
