Compact 1U rackmount NAS
The Qnap TL-R400S-US is a 1U rackmount network-attached storage chassis with four drive bays. It suits small offices or remote sites that need centralised file storage inside a standard server rack. The unit arrived on the market in 2021 and weighs 8.77 lbs.
Straightforward drive installation
Four SATA bays accept 3.5-inch or 2.5-inch drives and slide in without tools. The short 1.73-inch height leaves minimal finger room, so cable routing can feel tight. No drive carriers are included, and the front panel does not latch if a bay is empty.
Steady throughput for file workloads
Under sustained read or write loads the SATA links and internal backplane keep latency predictable. The passive cooling design relies on rack airflow, so performance stays consistent as long as the cabinet provides adequate circulation. Extended heavy transfers do not trigger thermal throttling in a properly ventilated rack.

Perguntas sobre este artigo
How can I confirm the TL-R400S-US is operating correctly after installing four SATA drives?
The front-panel LEDs show power status and drive activity for each of the four bays, and the management interface reports drive health once the unit boots.
What ships with the TL-R400S-US and what must I purchase separately?
The 1U chassis includes drive trays, rack-mount rails, and a power cord; four SATA hard drives or SSDs are not included.
Which capacity version of the TL-R400S-US should I choose?
The TL-R400S-US is a diskless 4-bay enclosure, so you select the total capacity by populating the four SATA bays with drives of your preferred size.
