Synology Expansion Unit DX517 – 5-Bay External Storage Expansion for DiskStation

Effortlessly increase your storage capacity with the Synology Expansion Unit DX517. This 5-bay expansion module is the ideal solution for businesses and power users who need to scale their existing Synology DiskStation. If your current NAS is reaching its limit, this unit allows you to add extra volume without any complicated setup. It is perfect for those managing large branding archives or extensive media libraries.

Seamless and Instant Scaling

The DX517 provides a highly flexible way to grow your digital infrastructure. Because it connects directly to your host NAS via a high-speed eSATA cable, you can add five additional drive bays instantly. You can use these extra bays to expand your existing RAID volume or to create a separate local backup destination. This ensures that your professional projects always have the space they need to flourish.

Reliable Hardware Performance

This unit is designed for maximum compatibility and ease of use. It supports both 3.5″ and 2.5″ SATA drives, giving you the freedom to choose between high-capacity hard drives or fast SSDs. The “plug-and-use” design means the host DiskStation recognizes the new drives immediately. Furthermore, the unit is built to be robust, weighing approximately 3.91 kg, which ensures stability on your desk or server rack.

Efficiency and Peace of Mind

Stay productive with a device that prioritizes uptime and convenience. The DX517 features hot-swappable drive trays, allowing you to replace or add drives without shutting down the system. Additionally, the deep integration with Synology DiskStation Manager (DSM) allows for easy monitoring and management. With a 3-year warranty, you can invest in your firm’s digital retention and visibility with total confidence.
