Product Details
Sonnet Technologies Echo 21 Thunderbolt 5 SuperDock Docking Stations with 10GbE for Mac, Windows, and Chromebook Computers - ECHO-DK21-T5
The Sonnet Echo 21 Thunderbolt 5 SuperDock, as the name implies, works with the current fastest connectivity port on the current generation of Macs. It has a total of three Thunderbolt 5 ports, allowing you to connect multiple high-data devices to the 120Gbps Mac connection.
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.
One of the Thunderbolt 5 ports is used for the uplink to the Mac, and also has 140 watts of power delivery. The dock has another five USB-C charging ports, which each operate at 10Gbps. There are four more USB-A, which all can connect at up to 10Gbps.
The connections continue with two Video and DisplayPort connections, so you can connect multiple displays along with other hardware. The list is rounded out by 10-Gig Ethernet for fast networking and Hi-Res audio outputs that support lossless audio at up to 24-bit 96kHz.
Equivalent in all other features, the Echo 21 dock was designed with an M.2 NVMe SSD socket to support storage inside.
Features
- Built-in M.2 NVMe SSD Socket (Echo 21 SuperDock only)
Enables users to install 8TB of storage with data transfers up to 3,300 MB/s. The internal storage is great for many uses, including pro content creation, application and media storage, and Time Machine® backups. - Two Thunderbolt 5 Peripheral Ports
Support Thunderbolt 5, 4, 3 and USB peripherals — including displays — and provide 15 watts of power each. When used with self-powered Thunderbolt devices, these ports support up to four devices in total via daisy chain connections. - 10Gb Ethernet Port
Adds blazing-fast 10 Gigabit Ethernet (10GbE) network connectivity via inexpensive Cat 6 or Cat 6A copper cabling. Backward compatible with 5Gb, 2.5Gb, and GbE infrastructures. - Two Video Output Ports
Connect a 4K@60Hz (macOS) or 8K@60Hz (Windows) HDMI display or a 4K@144Hz DisplayPort display directly with no adapter required. - Nine USB 3.2 Gen 2 (10 Gbps) Ports
Includes four 10Gbps Type A ports and five 10Gbps USB Type-C ports, all able to support super-fast 10Gbps USB NVMe SSDs at full speed. All the ports boost power to ensure that bus-powered SSDs with higher peak power requirements mount and operate reliably. The USB-C ports also support the Type-C Charging spec and can charge devices even when the computer is off, sleeping, or disconnected. - High Resolution Audio I/O
A hi-res audio codec (coder-decoder) supports the docks’ audio I/O jacks with high-quality, lossless audio – up to a 24-bit/192-kHz sample rate. It includes a 3.5-mm headset jack and a 3.5-mm microphone jack. Separate left- and right-channel RCA jacks provide line level output to powered speakers or a direct connection to a receiver, power amplifier, or mixer; they are also excellent for connecting self-powered studio monitors and other pro audio gear. - Rear Panel Computer/140 Watt Charging (Thunderbolt 5) Port
Placing the computer interface/charging port on the back panel allows for easier cable management. - ThunderLok Support
The Echo 21 docks feature an integrated threaded mount that secures the included Sonnet ThunderLok Thunderbolt connector lock, helping prevent accidental cable disconnections. - Aluminum Enclosure
Durable design efficiently dissipates heat while maintaining a compact footprint.
