Connectivity and Power Delivery

Thunderbolt 5 is the next evolution of Thunderbolt technology, building on the advances of Thunderbolt 4. While Thunderbolt 4 delivers up to 40 Gbps of bidirectional bandwidth, Thunderbolt 5 significantly expands available throughput. It supports up to 80 Gbps bidirectional bandwidth for data transfers, and can dynamically scale to as much as 120 Gbps of total throughput when combining data and high‑bandwidth display traffic — enabling demanding workflows such as high‑resolution video editing, multi‑display configurations, nd large data transfers.

Additional Thunderbolt-compatible cables (not included) are required.

8big Pro5 compatibility

8big Pro5 provides two downstream Thunderbolt 5 ports and one downstream USB 20 Gbps (USB 3.2 Gen 2x2) port, enabling flexible expansion for storage, displays and high‑speed peripherals. All downstream ports support devices that are USB 3.x and higher. Thunderbolt devices can be connected only to the Thunderbolt 5 downstream ports, which are backward compatible with Thunderbolt 4, Thunderbolt 3 and USB4. Connected peripherals operate at their own maximum supported speed rather than at Thunderbolt 5’s peak performance.

Examples of what you can connect

• Connect up to four devices using the two Thunderbolt 5 ports and the USB 20 Gbps port
• Support multiple displays, up to three 4K monitors or two 8K monitors
• Connect high‑speed external SSDs, including Thunderbolt 5 models such as LaCie Rugged SSD Pro5 and USB4 models such as LaCie Rugged SSD4
• Daisy‑chain two devices from a single Thunderbolt 5 port, for example, a high-speed SSD and a display
• Connect USB 20 Gbps devices via the integrated USB‑C hub port

Power delivery

8big Pro5 must be connected to AC power via its power cable to deliver power to compatible devices.
