Terramaster F4-425 & F2-425 NAS - Should You Buy?
Why It Matters
The review underscores how ultra‑affordable NAS units can meet basic storage needs, but their limited networking and CPU capabilities may hinder growth, guiding buyers toward models that balance cost with future‑proof performance.
Key Takeaways
- •TerraMaster F4-425 and F2-425 priced under $400, highly affordable.
- •T‑RIDE flexible RAID lets mixed‑size drives maximize capacity.
- •Built‑in TOS OS offers robust features despite minor glitches.
- •Single 2.5 GbE port and lack of M.2 slots limit performance.
- •Newer TerraMaster models provide better CPU, networking, and expandability.
Summary
The video reviews TerraMaster’s entry‑level F4‑425 and F2‑425 NAS devices, part of the 2025‑2026 series that target budget‑conscious users seeking an out‑of‑the‑box x86 Intel platform.
Key points include rock‑bottom pricing ($269 for two‑bay, $399 for four‑bay) combined with a quad‑core Celeron N5095, 4 GB soldered RAM, and a single 2.5 GbE port. The units feature TerraMaster’s T‑RIDE flexible RAID, allowing mixed‑size drives to be pooled without manual reconfiguration, and a sleek, well‑ventilated chassis with low power draw. The proprietary TOS operating system, now at version 6/7 beta, offers isolation mode, multi‑site backup, VPN, media apps, and Btrfs support, while still permitting third‑party OS installs without voiding the warranty.
The reviewer highlights concrete examples: the affordable price point compared with competitors, the convenience of T‑RIDE versus traditional RAID 5/6, and the ability to swap the internal USB boot key for a custom OS. However, the devices suffer from a single 2.5 GbE NIC, no M.2 NVMe slots, and an aging Celeron CPU, creating a performance ceiling that becomes evident with SSDs or multi‑drive RAID configurations. The HDMI port, present for years, remains unused beyond basic debugging.
For home users or small offices needing a low‑cost, ready‑to‑run NAS, the F4‑425/F2‑425 are compelling. Power users or those planning future expansion should consider TerraMaster’s higher‑tier Plus, Pro, or SSD‑focused models, or rival brands offering 10 GbE, NVMe caching, and newer Intel processors, to avoid bottlenecks and ensure scalability.
