UNITEK S1243BGY01-EU USB4 4-Bay M.2 NVMe SSD Docking Station 40Gbps 1-to-3 Offline Clone 32TB

Ultra‑Fast USB4 4‑Bay M.2 NVMe SSD Docking Station – 40Gbps, Offline Clone, 32TB Capacity
The UNITEK S1243BGY01-EU USB4 4‑Bay M.2 NVMe SSD Docking Station is a professional‑grade solution for users who need high‑speed storage expansion, easy data duplication, and multi‑drive management. With four independent M.2 slots, support for up to 32TB total capacity, and a 1‑to‑3 offline clone function, it eliminates the need for a computer during drive cloning.

Blazing 40Gbps Data Transfer
Equipped with a USB4 host interface (compatible with Thunderbolt 3 and USB 3.2), the docking station delivers total bandwidth of 40Gbps. Each bay operates at up to 16Gbps, allowing simultaneous read/write access to all four drives without bottleneck. Perfect for video editors, photographers, data analysts, and IT professionals.

1‑to‑3 One‑Key Offline Clone – No Computer Required
Clone data from a source drive to up to three target drives with a single button press. Insert the drives, connect the power supply, and press the cloning button. Four LED lights show progress (25%, 50%, 75%, 100%). When all lights are solid, cloning is complete. Ideal for mass deployment, backup, or duplication of boot drives.

Supports Large NVMe SSDs – Up to 8TB per Bay
Each bay accepts M.2 NVMe PCIe SSDs (M‑Key or B+M Key) in lengths 2230, 2242, 2260, 2280, and 22110. Maximum capacity per bay is 8TB, for a total of 32TB. (Note: Does not support M.2 SATA or mSATA drives.)

Tool‑Free Installation & LED Indicators
No tools needed – simply insert your SSD into the slot and close the retaining mechanism. Power, data activity, and clone progress are clearly indicated by front‑panel LEDs.

Premium Aluminum Construction
The aluminum alloy shell efficiently dissipates heat, ensuring stable operation even with four high‑performance NVMe drives installed. The compact footprint (98.0 x 57.0 x 16.8 mm) fits easily on any desk or in a camera bag.

Auto Sleep Mode for Energy Savings
After 30 minutes of inactivity, the docking station automatically enters sleep mode, reducing power consumption and extending the life of connected drives.

Wide Compatibility
Works with Windows, macOS, and Linux. Plug and play – no driver installation required for basic operation (UASP and TRIM may require OS support). Includes an external power adapter (required for operation).
