Product information

Description

The Synology RX418 is a 1U rackmount expansion unit engineered to seamlessly increase the storage capacity of compatible Synology NAS systems. By providing four additional drive bays, this unit allows users to scale their storage volume without the need for complex migrations or service interruptions. It is designed to integrate directly with existing RackStation infrastructure, ensuring that data management remains centralized and efficient.

Advantages

The primary benefit of the Synology RX418 is its ability to provide immediate storage expansion through a reliable plug-and-play connection. Once connected, the drives are managed directly via the Synology DiskStation Manager, appearing as if they were internal components of the main NAS. This simplifies administration and eliminates the need for additional software configuration. Furthermore, the unit supports energy-efficient operation through drive hibernation settings, which helps reduce power consumption and prolongs the operational life of the installed hard drives or solid-state drives.

Suitable for

Expanding storage capacity for 1U RackStation NAS systems
Creating dedicated local backup destinations for data protection
Businesses requiring scalable data management solutions
Environments where centralized storage control is essential

When it may not be suitable

This expansion unit is not a standalone NAS device and cannot function without being connected to a compatible Synology RackStation. It is also not suitable for users who require additional processing power or network connectivity, as it serves exclusively as a storage expansion module.

Key specifications

Drive bays: 4 slots for 3.5-inch or 2.5-inch SATA HDD/SSD

How to use

To use the Synology RX418, securely mount the unit into your server rack and connect it to your compatible Synology RackStation using the provided interface cable. Once connected, install your preferred SATA drives into the hot-swappable bays. The system will automatically recognize the new storage, allowing you to configure and manage the volumes through the Synology DiskStation Manager interface without requiring any extra software installation.

What to consider before purchase

Verify compatibility with your specific Synology RackStation model
Ensure your rack environment has sufficient space for a 1U unit
Confirm that you have the necessary SATA drives available for installation
Check your power supply capacity to accommodate the 100 W power requirement

Usage recommendations
