Twenty interfaces in one dock

The Sonnet Echo 20 Thunderbolt 4 SuperDock consolidates twenty ports into a single desktop hub. It adds three Thunderbolt 4 connections, four USB 3.2 Gen 2 Type-A ports, four USB 3.2 Gen 2 Type-C charging ports, HDMI, 2.5 Gigabit Ethernet, combo audio, microphone, RCA line out, an SD 4.0 card slot and an internal M.2 NVMe SSD slot. The included cable delivers up to 100W of power to the host computer.

For multi-display workstations

Creative professionals who need to drive 4K, 5K, 6K or 8K screens at 60Hz from Apple M series Macs, Thunderbolt 3 or 4 Windows PCs, Thunderbolt 4/USB4 Chromebooks or M series iPad Pro will benefit. Users whose laptops lack Thunderbolt 3 or 4 connectivity cannot use this dock. Buyers who need more than three Thunderbolt 4 downstream ports should look at a different solution.

Internal M.2 NVMe slot up to 8TB

An integrated M.2 slot accepts NVMe drives up to 8TB for internal storage expansion. The slot supports data transfer speeds up to 800MB/s, keeping large media libraries or project files inside the dock enclosure. The SSD is sold separately.
