Synology DiskStation DS925+ vs Synology DS923+

The DS925+ is a four‑bay desktop NAS that runs on a quad‑core AMD Ryzen processor, delivering fast file transfers and smooth multitasking for multiple users. It ships with Synology’s DiskStation Manager (DSM) operating system, offering a rich suite of apps for backup, file sharing, media streaming, and more. Designed for scalability, the unit supports up to 64 TB of raw storage and can be expanded with a PCIe 3.0 x4 slot for optional 10 GbE networking. Energy‑efficient features such as scheduled power‑on/off and fan speed control help keep operating costs low while providing enterprise‑grade data protection.

The Synology DS923+ is a 4-bay network-attached storage device designed for home labs and small businesses that need reliable, expandable file storage with built-in backup, media serving, and virtualization capabilities. Running Synology's DiskStation Manager (DSM) operating system, it offers a polished web-based interface for managing storage pools, running Docker containers, hosting Plex-style media libraries, and automating backups from multiple computers on the network. Dual M.2 NVMe slots allow SSD caching to speed up frequently accessed files, and an expansion unit can add five more bays for growing storage needs without replacing the whole system.
