Product information

Description

The Synology RX418 Expansion Unit Rack 1U 4-Bay for HDD and SSD with Serial ATA Interface is a dedicated storage expansion solution designed to seamlessly scale capacity for compatible 1U RackStation systems. Featuring a compact 1U rack-mountable chassis, this expansion unit integrates smoothly into existing server room environments, providing an efficient way to increase available data storage without requiring a complete hardware overhaul. It connects directly to the main server, allowing administrators to manage all connected storage drives through the standard DiskStation Manager interface.

Advantages

This expansion unit offers a reliable plug-and-play setup that minimizes administrative effort and reduces downtime during installation. Because it integrates directly with the host system, the additional storage drives operate as though they were internal to the NAS, maintaining consistent performance and centralized control. The unit supports both hard disk drives and solid-state drives across multiple generations of Serial ATA interfaces, ensuring broad hardware compatibility. Energy management features, such as configurable drive hibernation, help reduce power consumption and prolong the operating lifespan of the installed storage media.

Suitable for

  • Expanding storage capacity on compatible 1U RackStation systems
  • Creating a dedicated local backup destination for disaster recovery
  • Scaling data storage infrastructure in professional server rooms
  • Managing growing file archives and business workloads

This device is not suitable as a standalone network-attached storage system, as it requires a compatible host RackStation device to function. It may also not be suitable for server racks that lack available 1U space or environments that do not support the physical dimensions and power requirements of the unit.

Key specifications

  • Rack (1U) chassis type
  • Supports up to 4 storage drives
  • Compatible with HDD and SSD types
  • Serial ATA, Serial ATA II, and Serial ATA III interfaces
  • Dimensions: 480 mm width, 325 mm depth, 44 mm height
  • Weight: 4.28 kg

To use the Synology RX418, mount the unit securely into a standard 1U rack space and connect it to the corresponding RackStation using the designated expansion cable. Insert up to four 3.5-inch or 2.5-inch Serial ATA hard drives or solid-state drives into the drive bays. Once powered on, access the DiskStation Manager interface on the host server to initialize the new drives, configure storage pools, and manage data volumes according to your operational requirements.

What to consider before purchase

  • Verify compatibility with your existing Synology RackStation model
  • Ensure sufficient physical space within the 1U server rack
  • Check power availability and thermal conditions in the rack environment
  • Confirm that appropriate HDD or SSD storage drives are available for installation
Usage recommendations: To ensure optimal performance and longevity of your data infrastructure, configure automated drive hibernation settings within the management software to reduce energy usage during periods of inactivity, and regularly monitor system health and drive status through the DiskStation Manager interface.
