TerraMaster F4-424 Pro

Ranked #2 in NAS Devices

1033 LP on the category ladder what's LP?

TechRadar's top choice for most users: "the TerraMaster F4-424 Pro is our top choice for most users. During tests, we found this model delivered fast, secure file transfer." Four bays, modern Intel-class silicon and 2.5 GbE give it hardware headroom that the budget Synology boxes lack, and TechRadar's testing verdict is emphatic. It sits below the Synology plus boxes here because TerraMaster's TOS firmware and support track record is shorter and less proven over the long haul.

TerraMaster has just introduced its new F4-425 Plus NAS, which is a new addition that slots in just above the F4-424 . However, what we're looking here is not just a new SKU in TerraMaster's line-up of NAS devices, it's an entirely new product, which seems to have borrowed some ideas from Ugreen when it comes to the overall construction, but also heralds a return to aluminium for TerraMaster. The outer housing is a solid piece of extruded aluminium, into which a metal "skeleton" slots, to which some plastic parts and the motherboard is attached. It really causes the entire product to feel a lot more premium, making for a more solid feeling chassis.

TerraMaster is quietly pushing its NAS lineup a step further with the F4-425 Plus, and this one is clearly aimed at users who have outgrown basic 1 GbE boxes and limited upgrade options. On paper, it looks like a straightforward refresh, but the changes in construction, connectivity, and storage flexibility make it a very different machine than the older F4-424 or the original F4-425. The core layout is familiar: four 3.5/2.5-inch SATA bays, good for up to 120 TB when populated with current 30 TB drives. What changes the game is the addition of three M.2 NVMe slots. These are not an afterthought.

The overall power usage of the F4-425 Plus is slightly lower or on par with the F4-424, suggesting that the Intel Processor N150 is a smidgen more power efficient than the Intel Processor N95, but not enough to really matter. Admittedly the two Realtek 5 Gbps Ethernet controllers draw a little bit more power than the 2.5 Gbps version, but even in full use, this wouldn't be more than a single watt. As such, the F4-425 Plus is pretty power efficient for the performance it can deliver and there's nothing that sticks out here.

The TerraMaster F4-424 Pro NAS delivers a solid combination of performance, expandability, and ease of use in a compact 4-bay design.With its modern Intel platform, DDR5 memory support, and dual 2.5GbE networking, it represents a meaningful step forward from older NAS systems that are still limited to gigabit networking and lower memory ceilings. The inclusion of NVMe slots and Docker support further enhances its appeal for enthusiasts and power users.

The performance of the F4-24 is commendable, providing smooth 4K video streaming and efficient file transfers, which is crucial for creative professionals or businesses relying on large media files. The fan noise is relatively low, making it suitable for office settings or home use. While it may come at a slightly higher price point than entry-level NAS systems, the performance, flexibility, and features of the Terram F4-24 Pro justify the investment. Overall, it's an excellent choice for anyone seeking a powerful and reliable NAS solution.

UGREEN’s DXP4800 Pro, built on a Core i3-1315U with Quick Sync, and TerraMaster’s F4-424 Pro, pairing a Core i3-N305 with 32GB of DDR5, are both strong choices for a household running multiple simultaneous 4K or 1080p streams. Asustor’s Nimbustor AS5404T and Lockerstor 4 Gen2 cover the same ground on a Celeron N5105 platform at a lower price point, making them the better pick if your library skews toward 1080p rather than 4K.

5 GB ports make the F4-424 Pro particularly interesting for fast local networks. If you're looking for a diskless NAS that combines serious CPU performance with large storage expansion and fast networking, the TerraMaster F4-424 Pro is built around exactly that formula.

If you're looking for a power efficient NAS, this isn't it, as the much more powerful F4-424 Max was delivering similar power usage during heavy loads. Hopefully some of this can be chalked up to the fact that TOS 7 is still a work in progress, but it seems like the Intel Core 3 Processor N350 might not be as power efficient as one might think based on Intel's specs.

The F4-424 Pro arrived in early 2024 with a strong hand: an Intel Core i3-N305, 32GB of DDR5, and a build that put competitors under genuine pressure. Two years on, the company returns with the F4-425 Pro, and the result is a more complicated story than a straightforward generational step forward.

There are more affordable options available from this manufacturer, but the N300 processor has twice the number of cores found on the non-pro variant of the F4-424, making it more capable at multitasking while consuming less power.

Summary: TerraMaster F4-424 Pro packs an 8-core i3-N305 with 32GB of DDR5 RAM into a 4-bay chassis with easy alternative-OS support. The right pick for power users who want maximum hardware headroom and homelab flexibility.

Most compute for the money: The F4-424 Pro — but only if you’re flashing your own OS. The i3-N305 + 32GB out of the box is hard to beat if you never plan to touch TOS. Best appliance experience: The DS925+ . Accept no transcoding and the drive whitelist, and you get software that genuinely works for five years with minimal attention.

Choose the F4-424 Pro for Docker, virtualisation, and raw performance. Choose the DS925+ for software polish, ecosystem maturity, and long-term support. See the Synology vs TerraMaster comparison .
