Sonnet Releases Echo 20 and Echo 21 Thunderbolt 5 Docking Stations with 10 GbE

Sonnet Technologies, a US-based long-time provider of connectivity solutions for Mac, Windows, and Linux systems, has released two new Thunderbolt 5 docking stations: the Echo 20 SecureDock and Echo 21 SuperDock. Both target professional users looking for high-speed I/O, with the key difference being built-in storage support on the higher-end model. The two docking stations are mostly identical in terms of connectivity. Both feature three Thunderbolt 5 ports, a host connection capable of up to 140 W of power, and two downstream ports for peripherals and daisy-chaining. There are also nine USB 3.2 Gen 2 ports split between Type-A and Type-C, a 10 Gigabit Ethernet port with backward compatibility, and dual display outputs via HDMI and DisplayPort. Depending on the host system, the docks can drive up to four displays, with support reaching 8K at 60 Hz on Windows systems.

The Echo 21 adds an internal M.2 NVMe slot taking drives up to 8 TB, with transfer speeds reaching 3,300 MB/s. This makes it suitable for local media storage or backup use cases without requiring external drives. Both models feature high-res audio I/O at up to 24-bit/192 kHz, plus full-size SD and microSD card readers. Compatibility covers Apple M-series Macs, older Intel Macs with Thunderbolt 3, and Windows or Chromebook machines with Thunderbolt 4, 5, or USB4. The Echo 20 SecureDock is available now at $449.99, with the Echo 21 SuperDock following in late May at $499.99.
