Synology DX1215 II 12-Bay Expansion Unit 12x 3.5"/2.5" bays Tower3 Years Warranty

Easily add 12 bays to your DiskStation

With its 12-bay desktop form factor, the DX1215II provides generous storage expansion for Synology DiskStation1 whenever needed with minimal impact on the deployment footprint.

Online volume and storage expansion

Add a new volume to your storage, or seamlessly expand RAID volumes on Synology DiskStation without reformatting drives with online volume expansion through DiskStation Manager (DSM) to minimize service disruptions.

Expand DiskStation with Synology drives

Developed in tandem with Synology storage systems, Synology enterprise storage drives deliver proven interoperability and high reliability through rigorous validation and compatibility testing.

Simple setup and management

Plug-and-play design makes adding the DX1215II to an existing DiskStation simple. Unified drive management through DSM ensures health monitoring, storage allocation, and maintenance tasks are centralized and easily accessible to administrators.
