TerraMaster's 4-star 4-bay F4-425 Pro NAS is an all-in-one media and business hub — and it's dropped to $680 at Amazon

The TerraMaster F4-425 Pro NAS, a compact four-bay desktop system priced at $680 after a $120 price cut, is currently available on Amazon. Featuring an 8-core Intel N350 processor and 16GB of DDR5 RAM, expandable to 32GB, this NAS is powered by three M.2 NVMe slots and offers dual 5GbE LAN ports, delivering up to 1,010MB/s with link aggregation.

Dual 5GbE networking represents a significant upgrade from the previous generation's 2.5GbE, making it particularly efficient for large file transfers and multi-user environments. The third M.2 slot provides additional flexibility for caching compared to most other four-bay NAS units in this price range. The device's N350 processor runs cooler and more efficiently than its predecessor, which is crucial for a 24/7-running device.

However, the device is limited by its PCIe lanes, which affect both the M.2 slots and networking, causing some reviewers to consider this a NAS hampered by those constraints. Despite this, the TerraMaster F4-425 Pro NAS remains a powerful, efficient option for those who don't require 10GbE speeds or advanced features like 10GbE ports, Thunderbolt, USB4, or the ability to run demanding local AI workloads on the NAS itself.
