Professional reviewers consider the F4-424 Pro the most powerful media-class 4-bay NAS on the market, lauding its desktop-grade i3-N305 CPU, 32 GB DDR5 memory, dual 2.5 GbE, HDMI 2.1 and NVMe caching. They commend its cooling redesign and tool-free bays, but criticize the immature TOS software, absence of 10 GbE/SFP+ and the limited PCIe Gen3 ×2 M.2 bandwidth.
Everyday users love the raw performance for 4K streaming, quiet operation, easy drive swaps and fast initial setup. Common frustrations revolve around the basic TOS app store, occasional firmware bugs, throttled M.2 speeds and the desire for easier RAM upgrades and a built-in battery backup.
