Quick Connect NAS Product TB4 / USB4 Interface Direct Connection Guide

Feature Overview​

USB4 / TB4 (Thunderbolt 4) is a high-speed connectivity standard that uses the USB-C connector form factor, featuring high bandwidth and low latency, supporting high-speed data transfer and device expansion. The USB4 / TB4 interface on TerraMaster NAS is compatible with Thunderbolt devices, enabling a high-speed direct connection between your computer and NAS for fast data transfer.

Direct Connection Requirements​

  1. Your computer must be equipped with a Thunderbolt 3/4/5 port or a full-featured USB4 port. Standard USB-C ports use a different protocol and do not support direct connection.
  2. The connection cable must be Thunderbolt 3/4/5 certified.
Note
  • macOS is recommended for better transfer efficiency.
  • Windows systems may require installation of corresponding drivers. Actual connection stability and transfer performance may vary depending on hardware, driver version, and system environment.

Direct Connection Steps​

  1. Connect the NAS device to the local network and ensure it is accessible.
  2. Use a Thunderbolt cable, connecting one end to the TerraMaster NAS USB4 / TB4 port and the other end to the computer's Thunderbolt port.
  3. Log in to TOS, go to Control Panel > Network > Interface, locate the network interface starting with TBLAN, and set an IP address for it.
