TerraMaster U4 423 NAS scaled

Any links to online stores should be assumed to be affiliates. The company or PR agency provides all or most review samples. They have no control over my content, and I provide my honest opinion.

Today, TerraMaster has announced a new affordable NAS that will appeal to small businesses.

The TerraMaster U4-423 is a four-bay NAS, but rather than the desktop-style NAS products I have reviewed from them in the past, this is a rackmount NAS. It weighs just 3.2kg without drives and occupies just one rack unit being 40mm in height with a width of 440mm and a length of 360mm.

It is a well-specced NAS with an Intel Celeron N5095 quad-core processor with 2.0 GHz and a maximum turbo of 2.9 GHz. It is integrated with a GPU graphics card, AES NI hardware encryption and equipped with two 2.5 GbE interfaces and 4 GB DDR4 dual-channel memory (expandable up to 32 GB).

The U4-423 is configured with two 2.5 GbE interfaces, supporting 2.5 GbE high-speed network bandwidth. Link Aggregation provides a network bandwidth of up to 5 Gb.

The transmission speed can reach 283 MB/s (Seagate IronWolf 18TB x 4, RAID 0), and you can also use the built-in M.2 NVMe for SSD cache acceleration which significantly increases the storage efficiency of the disk array.

As for disk array support, you can have Single, RAID 0, 1, 5, 6, 10. You can also set up a hot spare.

The NAS also has a two USB3.1 port capable of 10Gbps, and this allows you to expand the storage by paring the NAS up with the TerraMaster D6-320 USB3.2 Gen2 External Hard Disk Enclosure that was launched in March.

Space-saving: TerraMaster U4-423 has a shorter chassis depth and takes up less rack space than traditional NAS, which is very useful for environments with limited space, such as home basements, small offices, computer rooms, etc.;

Easy to deploy: Due to its small size and weight, TerraMaster U4-423 is easy to deploy and install in smaller racks or cabinets, and it can also be more convenient for maintenance and management, such as media production, security monitoring, etc.;

Energy saving: Compared with large NAS devices, TerraMaster U4-423 has lower power consumption, which saves more energy and operating costs.

High-speed multimedia storage and streaming media playback

Users can store multimedia files such as audio, video and pictures in TerraMaster U4-423, and use professional multimedia server software to stream these files to other devices through the 2.5GbE high-speed interface, such as smart TVs, game consoles, mobile phones, etc., to form a family multimedia center.

Support Larger Storage Space Expansion

With the latest TerraMaster TOS 5.1 system, U4-423 supports the TerraMaster USB storage  series to connect to the NAS through the USB interface, and supports the creation of arrays and storage pools to greatly expand the storage space.

For example, an external 6bay 10Gbps USB3.2 hard disk box D6-320 can provide up to 132TB of additional storage capacity of TerraMaster U4-423.
