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.
