1U rackmount form factor
Mini-SAS host interface
SATA/600 drive interface
Integrated cooling fan
Rack-mountable chassis

Scale storage on your terms with the QNAP TL-R400S-US JBOD expansion enclosure. Designed for rack environments that need more capacity without a full array refresh, it adds four SATA bays in a dense 1U footprint and connects through Mini-SAS for direct attachment to a compatible QNAP host. That makes it a practical fit for teams that want to extend usable storage while keeping the primary system focused on performance. The rackmount design helps preserve cabinet space, while the SATA/600 drive interface supports broad compatibility with enterprise and nearline SATA drives. A built-in cooling fan supports thermal management in always-on deployments, and the JBOD architecture keeps expansion simple: add drives, map capacity, and keep workloads moving. For infrastructure teams balancing budget, uptime, and serviceability, this enclosure offers a clean way to grow storage without introducing unnecessary complexity.
