Triple-Bay Cloner and Dock

The Rosewill RS-N2S-CL accepts two M.2 NVMe M-Key drives and one 2.5-inch or 3.5-inch SATA drive simultaneously. It functions as a standalone offline duplicator or as a USB 3.2 Gen 2 Type-C docking station for Windows, Mac OS, Linux, Android and iOS. Each bay supports up to 4TB of capacity.

Tool-Free Installation and Cloning

Drives slide into the ABS chassis without screws or trays, and the 12V/3A power adapter supplies all three bays. Offline cloning starts with a button press, removing the need for a host computer during duplication. The compact 3.1 by 3.01 by 0.71 inch form factor weighs 0.34 lb, so alignment of the M-Key notch is the only step that can go wrong.

USB 3.2 Gen 2 10Gbps Interface Limits

The external Type-C link caps sustained throughput at 10Gbps, so the fastest NVMe drives will not reach their internal PCIe speeds when docked. SATA drives are limited by their own 6Gbps ceiling, and the single controller shares total bandwidth across all active bays. Offline cloning speed depends on the slowest source or target drive installed.

Questions about this item

How do I know the offline clone finished correctly on the RS-N2S-CL?

The dock shows progress LEDs during the clone; when all lights stay solid the copy is complete and each target drive should mount with the same capacity as the source.

What comes in the box and what must I supply for the RS-N2S-CL?

The package includes the three-bay dock, a 12V/3A AC adapter and a USB 3.2 Gen 2 Type-C cable; you provide up to two M.2 NVMe M-Key SSDs and one 2.5"/3.5" SATA drive.

Which bay should I use for a 4 TB SATA drive versus a 2 TB M.2 NVMe drive?

The single 2.5"/3.5" bay accepts the 4 TB SATA drive, while either of the two M.2 slots takes the 2 TB NVMe M-Key SSD; each bay supports up to 4 TB.
