SSDs & ELECTRONIC NOISE

After these exchanges with Richard, I rounded up all the SSDs on hand, plugged them into a test system, and put each one up to my ear, one by one. I have to report that my inserted comment in Larry article was not completely correct. With one or two SSDs, there is a tiny bit of intermittent bzzzzzz — but at such a low level that when my ear is >6" away, I can't hear it. In a PC, it would be completely blocked by the case or drowned out by other components, even in the very quietest systems. I doubt this is what Richard is "hearing"; it is too low in amplitude for even dogs to hear it, in my opinion. None of the Intel SSDs exhibited any audible noise. However, I listened to the SSDs only during normal operation — idle, write or read.
