Compact 4-bay SMB NAS with scalable performance
The DS923+ is a compact, four-bay NAS designed for small offices and prosumers who want strong local storage with easy cloud-like capabilities.

M.2 NVMe slots enable caching or storage pools to accelerate common workloads like media libraries, document sharing, and small-scale virtualization test environments.
