Hard drives are as ubiquitous as the desktops or they're made for. But as technology evolves, manufacturers continue to make these faster and smaller than ever before. Case in point: Samsung, which has developed the world largest hard drive, packing 16TB of storage in a 2.5-inch format. While the PM1633a (as it's currently named) could be considered an SSD, since there aren't any moving parts inside, there's no doubt it is a good ol' hard drive at its core.
