The Sonnet Echo 20 Thunderbolt 4 SuperDock utilizes Thunderbolt 4 to provide multiple ports and expansion options to your compatible computer with a single cable. Gain access to a variety of connections, such as Thunderbolt 4, USB 3.2 Gen 2, 2.5 GbE RJ45 LAN, 3.5mm audio jacks, and more. The HDMI 2.1 port allows you to connect an 8K @ 60 Hz display directly to the dock without the need for an adapter. There are also storage expansion options, such as the M.2 NVMe SSD slot and a SD 4.0 card reader.


The built-in HDMI 2.1 port on the Echo 20 allows you to plug in an external display up to 8K @ 60 Hz directly. An HDMI adapter is not required to achieve max resolution. The Echo 20 also features three Thunderbolt 4 ports, one for connecting to your host device and the other two for directly connecting Thunderbolt peripherals and accessories. The two Thunderbolt 4 ports support USB4 and USB 3.2 devices and even provides up to 15W of power. Also available are four USB-A 3.2 Gen 2 and four USB-C 3.2 Gen 2 ports.

2.5 Gb Ethernet


Featuring 2.5 Gigabit Ethernet, the Echo 20 supports a 2.5 Gb/s link speed over common Cat 5e (or better) cabling when used with a compatible Ethernet switch or NAS with 2.5Gb Ethernet support. This saves you the trouble of having to invest in an Ethernet adapter. Need to connect to a switch without 2.5Gb Ethernet support? The Sonnet dock can also supports 1 Gb/s and 100 Mb/s link speeds.

M.2 SSD Slot


The built-in M.2 NVMe SSD slot enables you to add up to 8TB of SSD storage (sold separately) to your system without having to connect a storage device to your Echo 20 or upgrading your computer. Installing the SSD is easy and straightforward. Simply remove the two screws securing a bottom panel cover, insert the SSD, and reinstall the bottom cover with the two screws.
