I've two machines tucked away near my desk & a sudden rise in the ambient hard drive rumbling has occasionally been an indicator that I should look into what's happening, usually it's just one of the larger torrents but it has also drawn my attention to a few bots going over my git server. It draws attention to an alternate sense (hearing) when it comes to systems monitoring & information delivery, Phones are the common culprit of obnoxious beeping, whistles and tones but this sound isn't an intentional interpreted interrupting noise, it's a direct line from the machine.
