    I have a three month old 2017 MacBook Pro 15 with 256 GB SSD. Has anyone else here noticed what I can only describe as a screeching noise when the SSD is being access.

    Never noticed it on other machines with SSD’s including my previous 2017 MacBook Pro 13.

    Thanks

    I don't think the SSD has any moving parts - so I would hazard to say it's unlikely that the SSD is making this noise.

    Coil Whine would be my guess. Real common on modern devices with a lot of components in close proximity. It is coming from electric circuits in the board or SSD. GPU cards and power supplies are notorious for it. Google "coil whine" and I bet you find a video with the same noise you are hearing.
