Are you in the market for a new computer? It’s amazing how much processing power the latest Mac® and Windows®, and Linux® computers with Thunderbolt™ ports offer, but thinness comes with a cost—there’s nowhere for you to install PCIe cards for the additional connectivity and processing capabilities beyond what’s offered by a computer’s standard ports. Sonnet’s Echo™ Express SE I (Thunderbolt 3 Edition) is a compact, desktop Thunderbolt™ to PCIe card expansion system that enables you to connect a single PCIe card to any computer with Thunderbolt 3 or Thunderbolt 4 ports.

Echo Express SE I: Compact Desktop Expansion
Echo Express SE I provides a single PCIe card expansion slot in a compact and light enclosure. Designed to accommodate cards up to 7.75 inches long and measuring a compact 5.6 inches wide by 8.6 inches long by 3.5 inches tall, the Echo Express SE I has a small footprint, yet it is large enough to support nearly every Thunderbolt 3-compatible PCIe 3.0, PCIe 2.0, and PCIe 1.1 card available.

Key Features:

  • For Computers with Thunderbolt 3 or Thunderbolt 4 Ports
  • 40Gbps Thunderbolt Interface
  • One PCIe 3.0 x8 Slot + Space for Daughter Card

  • Mac, Windows, and Linux Compatible

  • Technical Notes:
    • While the Echo Express SE I features a 40Gbps Thunderbolt interface, some Windows computers equipped with Thunderbolt 3 use an x2 PCIe lane implementation of Thunderbolt 3 technology that limits PCIe performance to 20Gbps.
    • Second Thunderbolt port supports USB 3.2 Gen 1 (5Gb) or Gen 2 (10Gb) devices when connected with proper cable or adapter (sold separately).
    • Full performance requires the use of the included or comparable 40Gbps Thunderbolt cables; look for the Thunderbolt icon AND the number 3 on the connector housings to identify these cables. Full performance supported by any Thunderbolt 4 cable.
    • ThunderLok 3 compatible specifically with Sonnet 0.5- and 0.7-meter Thunderbolt 3 cables.
