Here's a word you may not know...
solid state drive
Very similar to a USB flash drive, solid state drives offer an alternative means to store data. Traditionally computers store data on a hard drive, which has a number of mechanical, moving parts inside of it. These moving parts are prone to fail, eventually leading to a hard drive crash. Solid state drives do not contain moving parts which means they are generally considered more reliable. They also use less power and allow you to access the data stroed on them faster than a traditional magnetic hard drive.
