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.
