By now you probably own a USB flash drive, and if you are a certain age, you remember the Atari game cartridges of the 80s.

With memory becoming cheaper and the technology involved in physical on board memory, vendors have now begun creating solid state hard drives.

These flash memory devices install in your computer just like a regular SATA hard drive.  The difference is there are no moving parts so the on board memory is able to get from the device to the CPU and other components of your computer faster.

The above demo shows two Mac Book computers booting up at the same time, one with a physical hard drive and one with a solid state drive.
