But after restarting my ipad, i could now see all my files. And is the most capable dock i have ever tried. Worked great out of the box, connected it to my ipad pro then shows up on my "files" the connected samsung 970 evo plus inside the enclosure. Transferred all my files there, then after 20 minutes i can no longer see my files on the ssd enlcosure. Seems like all the files got deleted!!! Luckily i haven't deleted my original files on my samsung ssd yet. Review: The right ports and more - Pros: • Number of USB ports. You will be hard pressed to find a dock with as many USB A and C ports as this one has. • SSD slot. Great for backups or added storage. • Size. As with most Thunderbolt docks, this is large and heavy. You will not want to travel with it. But that is where your manufacturer’s power supply and a cheap USB-C hub come it. Cons: • No MicroSD card slot. You can use the SD card slot with an adapter, but most people are using MicroSD cards these days for everything except for photos. • Price. At $300 MRP, this is in the upper-mid range for quality docks. I do think the SSD capability and number of USB (C and A) makes it worth the price. I have had USB-C-powered laptops (a 2019 and a 2023 HP Spectre x360 13.3” models) for 3-1/2 years. In that time, I have used several cheaper USB-C hubs. While these can be great for business trips, I wanted something more powerful to have at my office desk allowing me to leave my normal charger at home. And so, I spent a couple of months talking with respected IT friends and doing my research for the best Thunderbolt dock for my needs. I wanted at least one (possibly two) HDMI 2.1 ports. One or two Thunderbolt USB-C outputs. Three or more USB-A 10Gbps ports. Headset combo jack. The Echo 20 SuperDock more than met those needs. I have my Samsung 32” 4K monitor plugged into the HDMI 2.1 port. A KYY 15.6” 1080p portable monitor plugged into one of the USB-C Thunderbolt ports. A Logitech Unifying USB receiver is plugged into one of the rear USB-A ports. My headset for Zoom meetings and audio recording is plugged into the headphone jack. Many Thunderbolt docks sacrifice the number of Thunderbolt USB-C ports in exchange for adding another DisplayPort or HDMI port. I prefer more Thunderbolt ports and fewer HDMI or DisplayPorts because that allows more flexibility. It is easy enough to use a USB-C-to-HDMI or a USB-C-to-DisplayPort adapter or cable. And many newer monitors are coming with USB-C video input. My Samsung 32” can do either USB-C or HDMI 2.1 input so I chose HDMI so that it isn’t using up a Thunderbolt port unnecessarily. My KYY portable monitor can use either HDMI or USB-C so I chose one of the Thunderbolt ports as that will provide it with both video and power resulting in fewer cables on my desk. I now just take my laptop back and forth from the office rather than also needing to remember a charger, mouse, and cheap hub. And I don’t have to fumble around with lots of cables. Just plug in the Thunderbolt cable from the dock to my laptop’s USB-C power port and I and up and running. And the ability to have an SSD installed in the dock means I am more likely to remember to backup my files more regularly. I installed a WD Black 1TB SN770 NVME into the slot in the dock, mounted the drive on my computer (YOU MUST DO THIS BEFORE THE SSD WILL SHOW UP ON YOUR COMPUTER), and then configured SyncBackPro to backup the desired folders onto the dock. I no longer need to plug an external drive into a USB port in order to do a backup. As long as I am connected to the dock, I just run the backup profile group. Some people have complained about not having drivers for Windows 11. You do not need any special drivers. Any drivers for the dock are included in Windows. If you are having issues with a specific device, it is not an issue with the Sonnet Echo but rather an issue with your device. ## Features - Twenty Interfaces: three Thunderbolt 4, four USB 3.2 Gen 2 Type A, and four USB 3.2 Gen 2 Type-C charging ports; HDMI port; RJ45 2.5 Gigabit Ethernet; 3.5mm combo audio; 3.5mm microphone; line-level R+L RCA audio out; SD 4.0 card slot; and M.2 SSD slot. - Support for 4K, 5K, 6K and 8K @60Hz Displays - Charge Your Laptop: Provides up to 100W through the included Thunderbolt 4 cable - Features an M.2 NVMe SSD Slot: Add up to 8TB of storage inside and obtain data transfer speeds up to 800MB/s (SSD sold separately) - Compatible with Apple M series Macs; Thunderbolt 3 Intel Macs; Thunderbolt 3 and 4 Windows computers; Thunderbolt 4/USB4 Chromebook; and M series iPad Pro ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0C9VTDXY6 | | Best Sellers Rank | #7,408 in Computers & Accessories ( See Top 100 in Computers & Accessories ) #563 in Laptop Docking Stations | | Customer Reviews | 4.3 4.3 out of 5 stars (224) | | Date First Available | June 30, 2023 | | Item Weight | 1.75 pounds | | Item model number | ECHO-DK20-T4 | | Language | English | | Manufacturer | Sonnet Technologies | | Product Dimensions | 9.63 x 4.25 x 1.38 inches; 1.75 Pounds | | Type of item | Electronics | ## Images ![Sonnet Echo 20 Thunderbolt 4 SuperDock - Image 1](https://m.media-amazon.com/images/I/71kb6PTRsXL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Stopped working and my files from my NVME got deleted *by F***O on November 8, 2023* Changing my rating to 5 since the problem i stated below was caused by my ipad that updated to the latest release of ios version at the same time i connected it to the dock, just coincidence i guess.

Adequate ports for all my devices and has sped up performance. I was able to install a memory card into the dock so also serves as portable drive. It doesn't take a sata ssd but I bought (acer FA200 NVMe Gen4 SSD 4TB, PCIe 4.0, M.2 2280, Read Speeds Up to 7200MB/s, Internal Solid State Drive for Laptop, Desktop PC and PS5 Upgrade - BL.9BWWA.150) on amazon that worked great. The company was very responsive and helpful in guiding me to the correct ssd specs. ## Frequently Bought Together - Sonnet Echo 20 Thunderbolt 4 SuperDock - Maxonar [2 Pack 3.3FT] Thunderbolt 4 Cable, 240W Thunderbolt Cable 40Gbps Sync 8K/5K@60Hz Display and for Thunderbolt 4, Thunderbolt 3, USB4, and USB-C Devices - OWC 28-Inch Thunderbolt 4 and USB-C Cable with 40 GBPS Data Transfer, 240W Power Charging and 8K Video Capability (Black) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/542373891-sonnet-echo-20-thunderbolt-4-superdock](https://www.desertcart.at/products/542373891-sonnet-echo-20-thunderbolt-4-superdock) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-04-27*
