TerraMaster F4-424 Pro vs Synology DS923+
Side-by-side comparison of features, pricing, ratings, and alternatives.
The TerraMaster F4-424 Pro is a high-performance four-bay NAS designed for professionals and businesses. It features an Intel Core i3 processor and dual 2.5GbE networking for fast data transfer and reliable connectivity. With its robust hardware and advanced software features, the F4-424 Pro is ideal for demanding applications such as data backup, file sharing, and multimedia streaming.
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.
