USB flash drive, jump drive, or thumb drive.Solid-state storage (flash memory) has replaced most magnetic and optical media as it becomes cheaper because it's the more efficient and reliable solution. This technology is found mostly on extremely large HDDs or hybrid hard drives.Īnother common type of storage is optical storage, which uses lasers and lights as its method of reading and writing data. Today, magnetic storage is one of the most common types of storage used with computers. Below is a full list of all computer storage used over the evolution of the computer. Today, there are three types of media used to store computer data: magnetic storage, optical storage, and solid-state storage. Are storage devices input and output devices?.What storage device has the largest capacity?.
