Synology DiskStation DS925+ vs Synology DS923+
Side-by-side comparison of features, pricing, ratings, and alternatives.
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.
Around $600 for the diskless enclosure.

Synology DS923+ Reviews
3.8 (4)Good, not great
Mixed feelings about Synology DS923+ after using it for a while. On the plus side, strong docker/virtualization support. That said, premium pricing versus building your own nas, which held us back from rating it higher.
Does exactly what we need
We've been using Synology DS923+ for a few months now and it's genuinely made a difference. Good community and documentation. One minor gripe: cpu can bottleneck heavy transcoding, but it hasn't been a dealbreaker. Would recommend.
Solid choice
I picked up Synology DS923+ a while back and haven't looked back. Strong Docker/virtualization support. No major complaints so far. Would recommend.
