Watch a hard drive at work, in slow motion and soaking wet.

Here’s a clever video, showing the innards of a hard drive at work in slow motion.

Hard drives work at very fast speeds as you’ll see.

Also worth mentioning that the hard drive arm is passing over the high-speed platters with about 3 nanometers clearance (that’s enough space for only 30 Helium atoms!).

That’s why hard drives are in sealed units and should be treated with some care. 

Given the high speeds and tolerances involved, it’s amazing drives work at all, let alone in the laptops we casually toss in our bags.

Also a reminder about the importance of backups — hard drives can’t be relied upon to keep data forever.
