Introduction

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. We think we would've preferred a different color on the aluminium though, as the silver and black does look a little bit odd, but that's really a matter of taste.

Under the hood, things have changed significantly as well, but more about that when we take a closer look at the hardware, but let's just say that almost everything is an improvement over the F4-424. The changes do come at a cost and we're talking about the monetary kind here, as the price has been bumped up by US$70 over the F4-424, but in all honesty, even this early in the review, it looks like the F4-425 Plus is worth the extra asking price, just from a build quality perspective. You do of course get a bump in processor, Ethernet and available NVMe slots as well, so it's not just the housing you're paying extra for here. Let's not get ahead of things though, as we need to put the F4-425 Plus through its paces to see if the upgrades are worth the seemingly reasonable increase in price vs. the F4-424.

Packaging and Bundle

The F4-425 Plus ships in a retail box which looks much like TerraMaster's other retail boxes and the NAS is tucked in between two foam inserts, alongside the accessory box.


A standard bundle of accessories is included, which consists of the power adapter, an Ethernet cable, a bag of screws, some labels for the drive caddies and some basic documentation and warranty documents. The power adapter is rated at 90 W and is once again from Edacpower.
