My PC is making a high-pitched squealing sound when copying data over the network to the internal NVMe drive. The squealing sound perfectly correlates with when Windows is showing high MB/sec write speed. When I’m copying a bunch of small files and the write speed falls to KB/sec, the noise goes away. When I’m writing a large file at 50 to 100 MB/sec, the squealing is very noticeable.

I have attached an audio clip here. I filtered out the low frequencies (just background noise) to make it easier to hear the squealing.

Anyone know what this is? Is it the NVMe drive itself? The sound is loudest right where the NVMe drive plugs into the motherboard.
