Examples of computer storage

Magnetic storage devices

Today, magnetic storage is one of the most common types of storage used with computers. This technology found mostly on extremely large HDDs or hybrid hard drives. 

Optical storage devices

Another common storage is optical storage, which uses lasers and lights as its method of reading and writing data.

Flash memory devices

Flash memory has replaced most magnetic and optical media as it becomes cheaper because it is the more efficient and reliable solution.

Online and cloud
