I mean GHz. Gb/s is a product of GHz and the width of the data path(bits). I'm focusing on the frequency because that is what you hear, not the the data path.
Got a tip for us?

SSD Noise?

It's a serial connection of 1s and 0s. Not an analogue qam signal.... What about it is operating in the gigahertz range? Do you have a source for this?
It has to be operating in the GHz range to move the 1s and 0s the the data rates we're talking about. We're not talking about a parallel communication protocol that moves 8/16/32 bits per cycle, SATA is one bit at a time.
I don't have a source handy at the moment, I just did the math.
Interesting, I can hear slight "scratching" noise from the SSD area too, when I scroll up and down! You can hear it accordingly with your scrolling (M4 512GB here)...
Is this really normal? :/
UPDATE 1: This "scratching" scrolling noise seems to be present when scrolling in Firefox, but not in Safari. I tried enabling Hardware Acceleration in Firefox and it seems to have pretty much solved the problem.
@madflava54: Is it the same in your case?

As long as your ears don't mind, I am going to bet nothing is going to blow up. However you dog may dive under the furniture.
I've never heard anyone refer to bps in hertz before but if it makes you happy... Nonetheless pretty sure human ears aren't hearing a 1.5 ghz frequency.
My work laptop as well as some PCs I have worked on make a noise that sounds similar to this whenever I drag windows around the screen. I've always wondered what this was caused by.
SSD's do make noise, I heard it loud and clear on the first Crucial I owned and on most of them since. The loudest I have ever heard is made by OWC, it screams. I do have good hearing, some but not all of my co workers can hear it when i asked them to verify that it was making noise upon file transfer. Voltage regulators and ANY chip that oscillates around 20khz or so can potentially make audible noise. Power Supplies, more so the cheaper ones, make noise too because they're full of Voltage Regulators. I imagine the magnetic pulsation of the circuits inside are causing the same thing a tweeter speaker does as they turn on and off. Im actually backing up a pc right now and i can hear it screaming in bursts, in sync with the backup program making steps forward as the buffer fills, then transfers to the destination drive, then reads again from the ssd. Anyone that thinks it has no moving parts and therefore can't make noise can think about a solid object like a rock falling to the ground, it will vibrate when it hits. Everything is a moving part when a change occurs inside it or to it. Hope this helps satisfy someones curiosity.
I got some of my info from here: http://www.tomshardware.com/forum/275173-32-making-high-pitch-noise
Why do you disagree? Have you never heard a powersupply whistling? I know capacitors going bad certainly cause the VR's to whistle.
Is the voice coming to similar to this one?

I have just received a new macbook and I have started noticing this mechanical noise coming from the top centre. I have tested many things such as running black magic speed test- no noise; copying large amount of files, no noise! But when i start doing some video encoding i.e when the cpu start getting used up then i hear this mechanical voice coming along the loud fans.
Can someone help me explain what this noise is please before I contact Apple.
Thanks

I handle mSATA and SATA SSDs, and CF cards daily at work. I can say they definately make a high pitched whine when being written to (usually we drop 4-8GB OS images to them).
If you'd like, I can record the sounds of a rMBP SSD in an Envoy Pro, and a couple of other SSDs, and post the recordings somewhere.
Edit:
Here's a clip I recorded: https://www.dropbox.com/s/coqtvwleydro5w7/rMBP SSD whine.mp4?dl=0
It's a 2012 rMBP 256GB Samsung SSD in an Envoy Pro, with the cover removed, and with Blackmagic Disk Speed Test running. You can hear this time read noise is actually more audible than write noise.
Sorry for the high noise floor, the SSD whine is quite faint, so just the rMBP fan noise starts to sound quite loud in comparison. The occasional beeping sound is an annoying quirk of the camera...
I've had a couple of Samsung, Crucial and Kingston SSDs, a couple of Apple ones (OEM Samsung), and the ones I handle at work are mostly made by ATP. Some SSDs seem to be noisier than others, but all of the ones I've used, whine.

Bumping this, i can hear the SSD make noise in my 2015 rMBP when working hard and i put my ear to the chassis.
Weird.
Maybe electrical noise being picked up and fed through the speakers, but i can definitely hear something.

Actually you are completely wrong, there are capacitors and crystals in there that can both resonate and make noise. Try doing your research before commenting next time.
