Hard Drives store information magnetically on metal disks and have moving parts, while an SSD stores information electrically in microchips so they have no moving parts.
Hard drives have been around a lot longer, are cheaper, and have larger capacities, but are relatively slow.
SSDs are newer technology, more expensive, much faster, but are generally smaller in capacity.
At least for the time being, SSDs are improving at an incredible rate.
