SoNNeTEcho 11 Thunderbolt 4 Dock

I bought this because I have a 2019 i9 iMac, and purchased two external USB-C SSDs (Kingston XS2000) to serve as backups (a 2 TB for Carbon Copy Cloner, and a 4 TB for Time Machine). Unfortunately, my iMac has only two TB ports, and I was using both of those to drive external monitors. Thus I instead had to plug these into its USB-A ports, resulting in poorer performance and frequent disconnection. Thus I realized I would instead need to plug these into TB ports, which this dock provides (it has three of them).It's a great product, and has worked without issue: With my Kingston XS2000's plugged into it, there are no more disconnections, and they appear to work just as well as they do when I tested them by connecting them directly to my iMac's TB ports. All the other ports also work without issue.In addition, since all the ports on my iMac are on the back, and thus inconvenient to access, it's a great convenience to have an SD card reader, USB port, and headphone jack all easily accessible on the front face.It's also nice that it's fanless, and thus silent. In spite of being fanless, it does not get hot.I only have two small criticisms:1) It's unfortunate that the fast USB ports (USB 3.2 Gen 2) are all on the back, and the one on the front is slower (USB 2.0), since I use the front USB port when I need to transfer files to or from a USB key, and thus have to wait longer for those operations to complete. If you needed to have one slow port, it would make more sense to me to put it on the back, where you could attach, say, a mouse or some other device that doesn't benefit from a faster interface.2) This is minor, but: The cable to the computer comes out of the front of the device. Since you're going to leave that attached permanently*, there's no need for it to come out of the front, and it would be cleaner to have it exit from the back. [*Even if you have a laptop that you need to unplug, you're probably going to unplug the cable from the laptop instead of from the device.]Also, a big-picture comment: In retrospect, if I knew now what I knew then, I would have instead purchased a fanless Thunderbolt dock that could accommodate two SSDs internally (instead of having a TB dock plus the two Kingston XS2000's plugged into it), since the former would be cleaner, and give better SSD performance. This is not in any way a criticism of this dock; instead, it's just that I now realize a different configuration would be more suitable for my needs. Sonnet does have such a device, but unfortunately it has a fan. SIIG has a fanless device, but I can't personally speak to its robustness.

Fungerar bra på intel dator med Linux. Bra docka,ljudet är bra,alla portar som den har uppfyller mitt behov.

robusto e stabile

como todos los dispositivos de la marca sonnet son caros pero son el top de gama, no hay otro igual, ofrece una calidad tecnológica sin igual en el mercado

If you have an iMac and you want more Thunderbolt expansion then this is the best way to do it. I paired it with an iMac 2020 and also with a Mbp 16” i9 and an M1X Pro 16”. No issue at all, no weird sounds like others say and the speed is what is supposed to be. I daisy chained an OWC M2 NvMe device, a BMD Ultra Mini Monitor and Ultra Mini Recorder, but also another Netstore NVME device and a Thunderbolt 3 monitor. All speeds are great, the only issue was that it forced me to upgrade to Big Sur as it requires 11.2 minimum OS. But apart from this, nothing to complain.Compared to other devices like CalDigit TS3 Plus or any other dock, it’s better, thought it might miss a pure USB-C port. But you can connect usb-c to the 3 TB4 ports it has and also connect a TS3+ to Sonnet Echo 11, so it’s better. I left it on the iMac 2020 for now, as it’s better used there since iMac has only 2 TB3 ports. But it’s future-proof, being TB4 (and backwards compatible to TB3).
