## Description

desertcart.com: Sonnet Echo 20 Thunderbolt 4 SuperDock : Electronics

Review: Big difference in performance and supportive vendor. - I've had dock for about 6 months and it has made a big difference in the performance of my computer. 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 desertcart that worked great. The company was very responsive and helpful in guiding me to the correct ssd specs.
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.

### ⭐⭐⭐⭐ The ssd port is great
*by T***N on April 27, 2025*

I've had some issues with the USB ports. If I plug an iphone or ipad into one of the type c ports, I'm assuming the power is overloaded... because the rest of the usb orts might start acting weird. I have a belkin dock which doesn't have that problem , so I use that. Aside from that its been stable
