As Dave said, they both store data and can be accessed via SATA connections, but the similarity ends there.
Solid State Drives (SSDs) actually have much more in common with RAM than with hard disk drives.
Hard Disk Drives are mechanical components that work rather like record players. The disks spin and a magnetic head adjusts to read or write to different sectors on the disc surface.
SSDs, on the other hand, electronically access and modify NAND flash memory chips attached to a Printed Circuit Board (PCB) via a specialized microprocessor called a controller. SSDs are more complex as a result of all this advanced technology, typically have a lower life expectancy than hard drives (although this varies in proportion to the type and amount of NAND flash memory they contain and the wear-leveling algorithms used by the controller), and cost significantly more, but they are also able to operate in extreme conditions in which hard drives would fail, can take much more abuse in general operating conditions without failing, typically consume slightly less power than hard drives, and can maintain much faster transfer and access times.
The durability and speed of SSDs along with falling prices based on the ability to make higher capacity flash chips for less money when using smaller gate technology (shrinking from 50nm down to 40, 30, or 20nm and smaller) is what is leading the increase in adoption of SSDs and the decrease in hard drive use, although widespread general use of SSDs will likely not happen for 2-3 more years.
