TerraMaster releases new short-depth rackmount U4-423 NAS



It’s the season for NAS companies to release short-depth rackmount servers as TerraMaster is outing the mighty new U4-423. Designed for businesses, this NAS is part of the company’s 2023 push with Intel-powered servers we’ve reviewed here previously for consumers. Let’s take a look at what you get for almost $700.

The highlight feature of the new TerraMaster U4-423 is the dual 2.5GbE networking interface, which provides bandwidth of up to 5Gb through link aggregation. Four available 3.5-inch drive bays can be used for the best NAS drives or smaller SSDs with a supported capacity of up to 88TB.

As well as the four bays, there’s a single M.2 slot for an SSD to be installed for use as a cache drive to speed things up a little. Being a 1U rackmount case with a depth of just 360mm, the TerraMaster U4-423 is incredibly compact, making it ideal for not only a data center but also a bustling office.

The Intel Celeron N5095 is more than enough for the server, thanks to its four physical cores that can burst up to 2.9GHz. Three 40mm fans keep everything cool inside the compact chassis and you can expect to see a power draw of up to 35W, depending on which drives are used.

TerraMaster makes some of the best NAS in terms of value and the U4-423 is another fine example for businesses. The TerraMaster U4-423 is available now from partnered retailers for $699.99.
