Professional reviewers commend the AS6704T for its powerful N5105 CPU, dual 2.5 GbE ports, and extensive PCIe and M.2 expansion options, calling it an efficient platform for content creation and future-proof upgrades. They also praise the quiet cooling system and modern software stack, while noting that full performance hinges on user-installed RAM and optional 10 GbE cards, and that missing power and weight data limit planning.
Everyday users praise the NAS for its easy, tool-less installation, fast M.2 caching, and reliable 4K streaming over a robust 2.5 GbE connection. However, they express frustration over the need for DIY hardware upgrades to reach peak performance and the lack of clear power and weight specifications.


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.
