An account circulates, with video, that shouting into a rack of spinning disks produced a measurable rise in I/O latency, attributed to vibration disturbing head positioning. No claim is made here about the magnitude, the method, or whether the effect reproduces outside the original demonstration.
Editorial judgements on a 0 to 10 scale, argued in the notes below and nowhere else. They order a list. They are not evidence and they never appear in a claim.
When latency moves and the queue did not, look outside the chassis before you look at the code.
Triage questions. Locate the original demonstration and the person who ran it, and whether a written method accompanies the video. What was measured, with what tool, over what window, and against what baseline. Whether the vibration mechanism is independently attested in drive vendor documentation rather than inferred from the demonstration. This is the rare lead in the inbox that could plausibly be REPRODUCED rather than only sourced, which would make it the first record in this repository to reach claim_status reproduced. That makes it worth more than its entertainment value.
