Noise (or the lack thereof)

As solid state drives have no spinning platters or moving parts of any kind, they are effectively silent storage devices. It is possible that there could be a tiny bit of electronic noise (typically a high pitched squeal) being emitted, either intermittently depending on task, or continuously, but we never heard a thing, even in the anechoic chamber with ear pressed right up against it. Frequency analysis also didn't reveal any tones that might have been generated at the edges of our audible spectrum.

Drive Comparison Tables

As always we present to you our most recent vibration, noise, and power consumption tables for previously tested hard drives. Tested SSDs were not included as they generated no vibration or audible noise. Use a perfect vibration score of '10' and our anechoic chamber's noise floor of 10~11 dBA@1m for acoustics if you want to compare any of the drives below to an SSD.
