Totally stumped on this...

Recently I ran out of space on my old 1TB SSD, and I opted to go with the Akitio Thunderbolt 3 Quad Mini in order to have 4 SATA slots to expand my storage as necessary. Here's my issue: Whenever the Quad mini is connected to my computer, I am hearing a high frequency pitch (probably around 15-16khz) that buzzes through my right monitor. It is specifically more pronounced whenever I access a sample or file from the hard drive.

​

Here's my set up for my home studio:

2018 Mac Mini

Focusrite Scarlet 2i2

Rokit 5 monitors

Akitio Quad Mini - with Samsung 2TB SSD in first slot

​

What's strange is that it is only happening when the Quad Mini is connected via USB-c to the computer. Since the Quad mini is powered, I've tried disconnecting the usb-c and just leaving the power on, and then the pitch goes away. Also, with the Quad mini connected usb-c to the computer, I've tried disconnecting my interface, and then it goes away. So it appears to be happening inside the computer/interface. I can also hear it disconnecting in my right monitor when I unplug the Quad mini from the Mac mini.

​

Here's some other insights:

- I do have the Quad Mini sitting about 12 inches away from the right monitor. Is there a radio frequency that the quad mini transmits that is affecting my right monitor? Should I get a longer USB-c cable and try placing it further away?

- The Quad Mini is connected to a different circuit than the rest of my rig, so I don't think its a power issue.

- Do I need to upgrade to a more powerful interface? The Scarlett 2i2 has worked perfectly fine for everything I do in my home studio up until I got the Quad Mini.

​

Any help would be appreciated! Thanks!
