Also known as a solid state drive, the SSD is one of the most well-known alternatives to an HDD. The latter is, however, the typical storage component that most computers and laptops come with – a hard disk drive. A solid-state drive is a device created to store data on your computer. Some tend to confuse it with a flash drive, but this only happens because it looks like a bigger and much more complex version of the more familiar USB stick. There are some similarities between the two of them, since they both have no moving parts, as opposed to an HDD.
