Vantec NST-DM12C31 Triple Bay Dock with Clone Function

Triple Bay Dock for Two M.2 and One SATA Drive

This enclosure accepts two M.2 NVMe modules in sizes from 2230 to 25110 and one 2.5 or 3.5 inch SATA SSD or hard drive simultaneously. It is built for users who need to access three different drives at once or duplicate data between them without a host computer. The aluminium chassis dissipates heat during heavy transfer workloads.

USB 3.2 Gen 2x1 Limits Combined Throughput to 10

All three bays share a single 10 Gbps upstream link, so simultaneous full-speed reads from multiple drives will saturate the bus. Sector-to-sector cloning runs at roughly 1 TB per 20 minutes when both source and target are M.2 NVMe drives. The dock does not accelerate cloning beyond the interface ceiling, and SATA drives operate at their native 6 Gbps ceiling.

Tool-Free Insertion with One-Touch Clone Button

Drives slide into the M.2 slots and the SATA bay without screws; a single button starts a standalone clone when the dock is powered but not connected to a PC. The most common error is inserting an M.2 SATA module into an NVMe-only slot, which the dock will not recognise. Ensure the source drive capacity does not exceed the target, and verify alignment before pressing the clone button.
