Branch Education | How do Hard Disk Drives Work?

Take a look at their PCB Assembly, for populating the components on your PCBs.

Have you ever wondered how Hard Disk Drives can store billions of bits of data within the volume of a short, small brick? Thinking about it, it's really truly incredible that a library worth of data, millions of photos, or thousands of videos can be stored in a device that costs less than $100.


Data storage has truly evolved to incredible densities over the past 6 decades, and in this video, we're going to see how exactly a Hard Disk Drive stores data, how it reads and writes data, and then the cutting-edge technologies that are continuing to decrease the size of each bit of data.
