Sonnet Echo SE I T5 Thunderbolt 5 Expansion System

Maximum PerformanceSonnet’s Echo SE I T5 Thunderbolt 5 Expansion System is a compact, single-slot Thunderbolt 5 to PCIe card chassis designed to let Mac, Windows, and Linux users with Thunderbolt or USB4 ports connect high‑performance, non‑GPU PCIe cards and unlock pro‑level audio, video, storage, and networking workflows at up to 6000 MB/s of bi‑directional PCIe bandwidth. Engineered for creative professionals who rely on laptops and mini workstations, this small‑footprint enclosure delivers PCIe 4.0 x8 performance, quiet active cooling, and an included Thunderbolt 5 cable so you can expand your system’s connectivity and processing power with near‑internal performance in an external desktop solution.

Create Expansion through a Thunderbolt PortLaptop and mini computers with Thunderbolt 5 ports offer tremendous processing power, but don’t have the PCIe slots creative pros need for connecting adapter cards to add specialized ports and processing capabilities critical to their workflows. Sonnet offers the ideal solution to overcome this limitation with the Echo™ SE I T5 Thunderbolt™ 5 to PCIe card expansion system. This compact, single-slot solution works with the latest Macs, Windows PCs, and Linux computers equipped with Thunderbolt or USB4 ports, letting you connect almost any Thunderbolt-compatible (non-GPU) PCIe card using the included Thunderbolt 5 cable.

Pro PCIe Card ExpansionEcho SE I T5 enables you to connect a pro PCIe card — such as video capture and playback; audio interface; SAS, SATA or Fibre Channel host bus adapter; multiport 10Gb or 25Gb Ethernet; or RAID controller — to add the ports and processors your computer lacks. Providing up to 6000 MB/s of bi-directional PCIe bandwidth to the installed card — twice that of Thunderbolt 4 or 3 — you’ll be able to extract even better performance with cards with ultra-high bandwidth requirements when connected to a computer with Thunderbolt 5 ports!

compact designMeasuring just 3.4 inches wide by 11.2 inches long by 5.8 inches tall, the compact Echo SE I T5 supports cards at a maximum of 7.75 inches long, making it compatible with nearly all Thunderbolt-compatible PCIe 4.0, 3.0, 2.0, and 1.1 cards. Not sure if a card you own or are considering is compatible? We’ve put together a compatibility list that identifies cards that are Thunderbolt compatible and organized by fit and power compatibility with specific expansion systems.

lightweight, rugged aluminum outer shellThe Echo SE I T5 system’s lightweight, rugged aluminum outer shell securely houses the installed PCIe card. Because it automatically powers on and off with your computer, there is no power switch on the enclosure, ensuring you don’t waste energy by forgetting to turn it off.

ultra-quiet operationEcho Express SE I T5 is engineered for ultra-quiet operation, making it ideal for noise-sensitive environments such as recording studios, broadcast facilities, edit bays, and shared office spaces. Its internal airflow path is optimized to allow the temperature-controlled, variable-speed fan to cool the installed card quietly and efficiently — even under peak load.

Thunderbolt 5 Cables and ThunderLoks IncludedSonnet includes a Thunderbolt cable engineered to deliver Thunderbolt 5’s full bandwidth and power delivery performance. The cable is fully compatible with Thunderbolt 5, 4, and 3, and USB4 computers. A Sonnet ThunderLok Thunderbolt connector lock is also included to prevent accidental cable disconnections.

Tomorrow’s Performance. Today.Echo SE I T5 is built with the features and quality you expect from a Sonnet expansion system, plus the Thunderbolt 5 interface you need for maximum performance. With 80 Gbps of bi-directional data speed — twice as fast as Thunderbolt 4 — and up to 120 Gbps for higher display bandwidth, you'll revolutionize your productivity.

More Than Just the Fastest External Interface AvailableEcho SE I T5 features a dual-port, ultra-high speed Thunderbolt interface that delivers the PCIe bandwidth needed to support most cards at maximum performance. While one port is reserved for connecting your computer; the secondary port enables connection of additional Thunderbolt or USB peripheral devices.
