Four-bay SATA dock with USB 3.1 10Gbps

The StarTech SDOCK4U313 is a four-bay docking station that accepts up to four 2.5-inch or 3.5-inch SATA SSDs or hard drives simultaneously. It connects to a host via USB 3.1 Type-C at 10Gbps and includes both USB-C and USB-A cables for broad compatibility. Two built-in 40mm fans provide active cooling, and an included universal AC adapter powers the unit.

Suits multi-drive workflows.

This dock is aimed at technicians, archivists and power users who regularly rotate several SATA drives for imaging, recovery, duplication or bulk data transfer. Independent drive doors, controllers, power switches and ejection buttons let you hot-swap each bay without disturbing the others. Users who only ever access one drive at a time will find the four-bay capacity and 78W power supply unnecessary.

USB 3.1 10Gbps host interface

The single specification that decides fit is the USB 3.1 Gen 2 connection running at 10Gbps. It sets the maximum throughput ceiling for all four drives combined, so sustained transfers from multiple SATA III drives will share this bandwidth. If your workflow demands dedicated 6Gbps lanes per drive, a different topology is required.

Questions about this item

Will the two 40 mm sleeve-bearing fans need replacement after long-term use?

The enclosure uses two 40 mm sleeve-bearing fans; sleeve bearings can wear over time, so fan replacement may eventually be needed.

Does the USB 3.1 10 Gbps link or the SATA III 6 Gbps drive interface become the bottleneck first?

Each SATA III drive tops out at 6 Gbps, while the host link runs at 10 Gbps, so the SATA interface limits sustained throughput per drive.

How much heat and noise should I expect when all four bays are running continuously?

The unit draws up to 78 W from its 12 V DC supply and relies on dual 40 mm fans for cooling, so expect moderate airflow noise and warm exhaust under full load.
