The Synology DX525 is a desktop disk array that adds five additional drive bays to a Synology DiskStation for expanded local storage. It supports both 2.5" and 3.5" SATA HDDs and SSDs, offers plug-and-play setup and hot-swap capability, and integrates with the host NAS through DiskStation Manager (DSM) for online volume expansion. The compact black chassis is suitable for small and medium business environments where seamless capacity growth is required.

Advantages

DX525 enables storage expansion without downtime by providing hot-swappable bays and on-the-fly volume growth via the host DSM. It can act as a dedicated local backup volume to protect data on its own disks in case of host failure. The unit is compatible with Synology drives for consistent performance and is covered by a three-year limited warranty with optional extended coverage.

Suitable for

  • Expanding storage capacity of a Synology DiskStation
  • Local backup volume for data redundancy
  • Small and medium business desktop deployments
  • Environments requiring mixed HDD and SSD support

Key specifications

  • Model: Synology DX525
  • Supported drives: 2.5" and 3.5" SATA HDD and SSD
  • Number of drive bays: 5
  • Chassis type: Desktop
  • Colour: Black
  • Weight: 2.46 kg
  • Interface: Serial ATA (via host DiskStation)

How to use

Connect the DX525 to a compatible Synology DiskStation following the host's expansion port instructions. Install supported 2.5" or 3.5" SATA drives into the trays, then power on the unit. Manage and integrate the additional bays through the host NAS DiskStation Manager (DSM) to create or expand volumes. Drives are hot-swappable, allowing replacement or addition without shutting down the system.

Recommendations

Use Synology-certified drives for best reliability and consistent performance. Configure the DX525 as a separate local backup volume if you require dedicated on-site data protection, and consider extending the warranty for longer hardware coverage.
