What are some commonly known facts that are too bizarre for you to believe to be true? (lemm.ee)

For me it is the fact that our blood contains iron. I earlier used to believe the word stood for some 'organic element' since I couldn't accept we had metal flowing through our supposed carbon-based bodies, till I realized that is where the taste and smell of blood comes from.

How about the new 2Tb m.2 drives? Not only vastly larger yet still, transfer speeds are also insane. I once had a computer with a 20Mb hard drive, current drives transfer 600-1200mb per second.

Not so impressive, of course its faster when its smaller. The data have to travel shorter.

Jk, it is damn impressive!

Actually, that's true! It's not significant enough to affect the throughput directly, but when you transmit data on parallel leads, they have to be roughly the same length in order to keep the signals synchronised with the time frames when they are received. Otherwise part of the data might not arrive in time. The higher the throughput (and shorter the frames), the greater the leads' lengths affect the timing. This is why you often see long squiggly leads on circuit boards - they extend the shorter leads to roughly the same lengths.

Eh, parallel hasn't been used for a while already. SATA literally means "Serial ATA" and no longer uses parallel connections. I haven't seen parlallel connectors since like a decade or so

I wasn't talking about connectors, I was talking about circuits inside the devices. Even if something is as simple as a clock and a data signal travelling in parallel, timing is still an important factor.
