I recently bought an OWC ThunderBay RAID enclosure with 4 spinning disks. The speed is great; the noise is not.
I bought it to replace a NAS that I kept in a cupboard at the other end of the house and I had forgotten how noisy drives are.
I’ve put a folded towel between it and my desk to absorb some of the noise, but it’s still not silent.
Just a word of warning, really.
